Operating System Penbex OS - in search of cheap solutions

The advent of new operating systems - a rare event, even more so. when it comes to operating system for handheld computers. Therefore the news of the release of handheld machines running the original Penbex OS has caused us increased interec. We have long been accustomed to the balance of forces on the PDA market, where the ball is ruled by Microsoft with its Windows CE and Pocket PC and the company Palm. The situation has not changed and with the cessation of production of keyboard Pocket PC Psion, as these machines occupy a niche and compete with besklaviaturny PDA (Psion rooted causes of the failure, most likely in a general decline in demand for small computers with built-in keyboard, and not in some kind of total dominance of the Pocket PC and Palm). As a result, Psion come to grips with software development for mobile communication devices, and the alignment of forces on the PDA market has remained the same as it was - with a small margin of Palm computers, and heightened pressure from the rival platform with the operating system from Microsoft. The main reason for constraining growth in demand for handheld and as a result of technology development - the high cost of small computers for the end user. Handheld computer - a device combining and optional. It can not function without regular synchronization of data between a PDA and a desktop machine (or laptop). This tool, a means of rapid access to stored pre-information off-line image viewer, text and multimedia files and more. Pocket PC, as well as any personal computer can be called "Player Programs". But this PDA software are inferior in terms of functionality, versatility and ease of data processing programs for the "big" cars. In addition, the PDA is not (and still can not be) sufficiently deep and fast means for storing large amounts of information. It is indeed "a computer in the palm" - a miniature digital device for reading and sometimes put in the memory typewriter small amount of data. In principle, without a handheld computer can easily do without. In the end, the possibility of traditional books, paper notepad, electronic calculators and watches are far from exhausted. And here in the foreground price Pocket PC. If entry-level cars were selling for 50-100 dollars (talking about current models, on sales of obsolete machines cost $ 100 and below are not uncommon), would be a long time we reflect on the appropriateness of their purchase? Large print runs of the issue (and, of course, sales), electronic notebooks only support this idea. But the ultimate cost of a pocket computer composed not only of the price of hardware and applications. The lion's share of the cost of the operating system. On the example of the very low-cost PDAs based on Windows CE 3.0 - Casio Pocket Manager BE-300 - we can see that only the manufacturer's refusal of the application of the software package from Microsoft (in the BE-300 used only the core operating system and core applications are developed independently) allowed to market a Pocket PC PDA-class retail value of less than $ 200 ($ 199 in the U.S., Russia, these computers are up to 75 dollars more expensive). That is, savings of at least $ 150. Nearly 80 percent of the final price Casio BE-300! Is this not a reason to actively seek alternative solutions - at least to get the major players in the PDA market to temper their appetites?

What return?

Attempts to develop a new alternative operating system have been made since the advent of handheld computers. The most glaring example - the various versions of Linux, tailored for use on PDAs. Alas, a lot of success so far failed to get anyone, although Japan and the U.S. computers preloaded with Linux operating system sold and used by certain demand (otherwise would not have produced). The reason for the prolonged delivery "of mobile version of Linux is in the system itself. For Pocket PC is too "heavy" and functionality is redundant. In this sense, redundant and Windows CE, but we already know what resources were attracted by Microsoft to promote its product - even after the apparent failure of the first version of Windows CE, and based on its devices.Operating system Windows CE and Linux should be considered as a basis for the Pocket PC-class Hi-end, approaching the cost and performance to a portable personal computers. This is a true multimedia station, pocket-sized, largely designed for entertainment, for playback of digital audio, and viewing of multimedia content - a full-color graphics and video. Most users, polls show, it was necessary electronic notebook with a well-developed service and the ability to transfer to your PDA the data needed in their daily activities. Stop whether simple models of Palm users with monochrome screens, lack of computer resources for high-quality audio reproduction, a modest computational power of the processor or the impossibility of displaying information in color? None. Most owners of these machines is quite happy with their digital assistants, and is not particularly want to change it to a newer model. The principle of reasonable sufficiency, which guides many PDA users the choice of a small computer that is not beneficial to the manufacturer, but by and large - and the consumer. Try to find in the computer world, such longevity as a Palm. But relatively "fresh" model differs from the first m125 Palm Pilot cars are much smaller than, say, computers with Pentium III processors from the Pentium IV. In the first case, productivity growth is negligible, and the capacity of programs, virtually unchanged. In the second case, we can talk about productivity growth at times and qualitatively new opportunities in processing, for example, graphics and video. Whatever it was, but "race frequencies" in the world of handheld computers has begun. So far, only the family Pocket PC, and Palm does not blowjob cup, if the company intends to remain among the world's leading manufacturers. And yet the army of simple computer users with modest computing power is huge (and increasing with the change of generations of handheld computers, as the life cycle of the CPC long-lasting than that of personal computers - at least 3 years, and for the Palm, and even more) to ignore it. Both Asian (mainly Taiwanese) companies are active in this area. The first noticeable and, judging by the shelves, an unsuccessful project was an operating system for computers called palmopodobnyh MineOS, developed by Axisoft Technologies for the company MSI, which released the Chinese clone of Palm - computer EZnow. This operating system was written in the flash memory machines, and could be optionally replaced by a "native" OS. The program's interface and core application in practical use can be considered more comfortable than the palm `-native. In particular, the window of handwriting information EZnow appeared on a call, as workspace systems Graffiti this computer has been replaced by the SIP application buttons. Some revolutionary differences MineOS of Palm OS could not be found, except that one - an alternative operating system was according to the manufacturer open and completely free. But why - was? Maybe somewhere (in China or other countries), it lives. But we have not developed. And now, at the last exhibition in Hanover, the public was presented the second version of the new operating system from the company Penbex Data System. The first version Penbex OS appeared a year ago. But today the company announced its product as the basis of no less than for even a single hardware platform handhelds. At this time - the most affordable in the history of technology development digital assistants.

Sheep in Sheep's Clothing

Break new platform at a relatively established market (relative to - because handhelds are progressing at breakneck speed), it is almost hopeless.Need some fundamentally new quality, which could distract potential (and actual) users of handheld computers from the now familiar families of Pocket PC and Palm. Incidentally, the devices based on Penbex OS live not only on paper. They are already available and like to sell. While this is nine models with monochrome screens. But none of these computers apparently not yet reached the foreign markets, and therefore only known Taiwanese user (although it is possible that computers are already available in neighboring countries in the region). The main advantages of the system, designed to "win" the acknowledged leaders, it's complete openness and low cost (explicit indication that the system is completely free, I have not found). The new operating system puts certain demands on the hardware. Curious to see what it is, the family computer Penbex. Here is a brief list of the technical characteristics of a typical PDA running the new operating system - a device the same as other models, even in minor details. The only difference is in the design of the hull and in the arrangement of control buttons.

Features:
• Central Processing Unit - Motorola DragonBall VZ328 such a frequency of 16 MHz
• Touchscreen monochrome 4-level grayscale display and dims. Passive matrix. Screen resolution - 160x160 pixels. Operating System Penbex OS supports the conclusion of the 16-bit color, but devices with a color screen on the market yet.
• The system itself and the main applications are written to flash memory 512 KB (on some models - up to 4 megabytes).
• Memory - 8 MB. Type of Memory - EDO or SDRAM (ie - no flash).
• As a source of supply for all machines (I mean already produced computers) uses built-in lithium ion battery. Voltage - 3 B.
• All computers are equipped with an infrared port (the operating system supports far only the wireless exchange of data between two PDAs, but not connected to a laptop or a desktop machine), a piezoelectric buzzer as the system dynamics, exit to stereotelefony (MP3 player is implemented in hardware, software and audio included in the composition of the main applications in the operating system)
• To synchronize with your desktop computer using a serial port RS-232C, USB support is missing.
• As an expansion slot is used CompactFlash. However, the operating system, except cards CF, supports a standard MMC card and SD.
• Dimensions and weight characteristics of new computers in general coincide with similar computers family Palm.

Programmers are likely to be interested in the fact that Penbex offers everyone a free SDK with emulator software for Windows. In this operating system provided file system support FAT16, support at the system level of work in dBase3, API-function calls, MP3-player and library work with SD-card support for color displays (Penbex version 2.x). What good, then - well. Development tools integrated with Visual Studio 6.0, which certainly is convenient for programmers who are accustomed to this IDE.

What's on the horizon?

How much do you think the chances of this Penbex grab their piece of the total market pie? It seems to me - quite a bit. Operating system interface quite crude.More on-screen buttons next to the area handwriting (six instead of four in Palm). Slightly differently drawn icons of programs ... The screen is not impressive at all, not to say that is depressing ... From time to time the market appears cheap computers with unique operating systems. They are slightly below the level for Palm, but not too much of them behind. Example - Pocket PC Pocket Viewer from Casio, which are heavily advertised in Russia. Like it is a good machine (on the quality of the screen, if only to read books, work with spreadsheets and playing simple games, they are perhaps better than monochrome Palm `s, although it does not support greyscale), but something about her all the same lacking. Namely - the popularity. As a result, software written by amateurs or those computers, or by the manufacturer. The total number of programs for the Casio PV will be hardly one hundredth of the total number of applications for Palm. And maybe less. No, I saw a hand-held computers Penbex any advantage over the machine from Palm. Moreover, the position Penbex worse than that computers with the operating system EZnow Mine OS. There's a unique change the operating system on the Palm OS - a pushover (as when buying a computer only pay for the hardware if the OS is indeed free of charge). Get it with a computer-based Penbex OS? There is quite a different logic implementation of the management of hardware buttons (in this part of the CCP Penbex resemble an amazing hybrid computers, Palm and Pocket PC). In my opinion, Penbex and companies who make a bet on this operating system, there is only one way to succeed - to release a massive model of Pocket PC to an extremely low price. Nothing other than cost, the new platform is not able to attract. This, alas, yesterday ... However, speculate about hypothetical delights and drawbacks - it stupid and useless. Wait and see. Perhaps the developers udast'sya bring it to an acceptable level and make the CCP property of the broad masses. In any case, the company Penbex Data System should say thank you for some variety, it has introduced a Pocket PC user. Or hope for this variety. The authors, translation:

Smart handheld assistants. Part I - The mobile operating system

Nowadays it is difficult to imagine anyone that avoids a mobile phone or music player. Flight of the scientific and technical ideas spawned a variety of devices for work and entertainment. One of the most common devices of this kind was the mobile phone, now overgrown with so many features, the phone began to call the new buzzword "gadget". However, devices from different manufacturers have a different functionality, some functionality you need is one device, some - in another. In this confusion comes to the rescue universal mobile computer. What is it? The answer can be found in our new articles on the mobile multi-function computers. Today we offer you to familiarize with the general principles for constructing smart handheld devices, and we decided to start from scratch - operating systems. The fact that it is, you know, after reading the first part, called "Mobile operating system."

Pocket assistant - who is he?

We began the article with an ulterior motive to mention cell phones. Today, many quite functional, more or less advanced the tube, but the market is also well represented, and handheld computers (PDAs) and smartphones, and communicators, and specific device - navigators. So what are all these devices? Of course, the tube or the player (even advanced) - is a thing in itself, such devices are designed for any particular purpose and objectives, and all the capabilities of these devices is strictly nastrogo built into the firmware, but to add something new to most change the device to the one that has the desired function. The unilateral lack PDA, communicators and smartphones. This was made ​​possible thanks to the fact that we have constructed many models of these devices on a common platform, called the Operating System (OS), almost the same as the well-known desktop. As you probably guessed, the operating system makes it possible not only flexible configuration and installation programs, but also writing of any application to suit your needs, so called smart devices and smart - they can be almost anything that can be desktop or laptop. On the market today there are several best-known operating systems: the ubiquitous Microsoft family of Windows Mobile, Symbian, Palm, as well as some less common operating systems such as Mac OS X or Linux. Let us consider the peculiarities of each of these operating systems in detail.

Operating systems for mobile devices

The family of Windows Mobile

Most famous, Microsoft supplies the market with not only the operating system for home computers, and handheld computers, smartphones and communicators. Windows CE - a compact version of the operating system for handheld computers (Handheld PC) and embedded systems. This system is very similar to the desktop version of Windows, but has nothing to do with it. The main feature of this OS is the ability to work with a small amount of RAM (5 MB), as well as support for mobile processor architectures ARM, MIPS, Hitachi SuperH (mobile processors) and even x86 (desktop processors).

Windows CE interface is very similar to the desktop version of Windows

Windows CE interface is very similar to the desktop version of Windows

In olden days this operating system is used in handheld computers, which are functionally not far removed from the notebook, and now Windows CE is a key platform for the construction of car navigation that allows you to create multi-function devices with multi-media bias.The fact that Linux not only supports the installation of third-party software, but also has a multi-tasking, allowing the device to Windows CE have a very good set of features. Naturally, the support and touch screen. Several years ago, CCP made on this platform (Casio model from Cassiopeia), today interface Windows CE (fifth edition) can boast of automotive and handheld navigation devices, is especially famous among them models from Nokia, Mitac Mio, LG, Clarion, GlobalSat, Pocket Navigator and others. This multifunction device is extremely useful in the car, especially on long journeys to unfamiliar places - just will not get lost.

In the olden days was used in Windows CE handheld computers. In the photo HP Jornada 680

Pocket Navigator PN-4300 operates on the Windows CE

Thus, Windows CE - a specific OS with a fairly narrow range of applications and more often in the professional sphere. Windows Mobile - the further development of Windows CE. Common of these is the OS kernel, the interface is radically different, in addition, Windows Mobile supports core processor architecture ARM. Today the actual Windows Mobile (WM) version 6. WM 6 is divided into three groups, each to their device, so, Windows Mobile 6 Professional is designed for communicators and includes a module for making phone calls and touch screen support.

Windows Mobile 6 Standard lacks support for touch screen and is designed for smartphones.

Finally, WM 6 Classic does not have a phone module at all, but it has touch screen support, and as you might imagine, is designed for PDAs.

The main features of the OS family of Windows Mobile are: flexible adjustment of virtually all parameters, support for interface skins, installing third party software (players, games, navigation software, calculators, dictionaries, etc.) that significantly expands the capabilities of the device with WM. The operating system already contains many features - it's the messages (SMS, e-mail), media player, Internet Explorer, calendar, notes, address book - that is a standard phone and PDA functionality. By design reminiscent of a desktop operating system Windows, but have little to do with it, however, those who are accustomed to a home Windows will be psychologically nice to see familiar colors and logo. Strain WM, taken from Windows CE - the open architecture. This opens up unprecedented opportunities to install additional software, you can even replace and build on standard software WM. However, this feature makes the system less stable - the more established programs, the greater the likelihood of conflict. Of course, WM has a multitasking - that is, on such a device can run multiple programs and work with them (eg, listen to music, view photos and surf the Internet). Chronology of different versions of Windows Mobile is shown in the table. Setting WM - lesson quite fascinating, so many of you will find this operating system all that we need to configure - interface speed, add / remove functions, installing different drivers, software for networking, games and more. In general, Windows Mobile - Operating System for those who like to delve into the settings and find out for myself something new in technology, in short, is technically advanced person, but having spent a couple of weeks on the development machine, you'll be pleasantly surprised by its versatility and functionality , moreover, that all the tweaks available through the registry, as a home PC. Concerning software, we mention that for the WM represented a huge number of third-party software - business applications, alternative browsers, for ICQ, reading books, calculators, multi media players and more, for every taste, just a list of quality games is not so extensive - in fact WM was originally intended for business users, but those games that are available - a very attractive and well made. And, by the way, yet for Windows Mobile there are practically no viruses.

Family of operating systems, Palm OS - Mobile pioneers

Palm OS - one of the first mass of operating systems for handheld computers. Around the same time, the CCP have been called PDA - personal digital assistant. Palm OS appeared in 1996, but much earlier had invented the method of handwriting text lain based Palm OS. Palm OS-based manufactured mainly PDAs and Smartphones Treo. Treo smartphones are distinguished by QWERTY-keyboard and touch screen, of course, they have a modulus of calls that enhances their capabilities as PDAs. Of course, having a touch screen in the Treo allows you to rank them for communicators, but the company palmOne another opinion - that the company is positioning as the Treo smartphones, but the classification will be discussed in the next part of this article.

Palm OS Garnet 5.4

Palm Treo 680

The most popular version of Palm OS - Garnet 5.4, this version is used in almost all modern PDAs and communicators Palm. The big plus is the excellent Palm OS address book and organizer, the likes of which no one has a single operating system, which is not surprising - because Palm was created as a portable database. A distinctive feature of all the devices based on Palm OS (except for Treo or TX) is separate from the screen area for drawing characters that are typed. Supports work with documents MS Office, and this function fairly well worked out even better than the Microsoft Windows Mobile. Finally, a negative feature of the Palm OS is the problem with switching encodings (KOI-8, Unicode, Win-1251) and part-time multitasking, for example, you can run the background listening to music (so the screen can be displayed only one application, however, that still need to user?). In the standard Palm OS contains the basic applications: Documents To Go for document Office (Word, Excel, Power Point), Calendar, Contacts, Calculator, File Manager, an Internet browser (designed based on the NetFront), Mailer (who knows everything underlying protocols and supports multiple mailboxes), Real One player, viewer videos and photos, various utilities. Palm is perfect as a reader electronic books, in conjunction with a mobile phone can access the Internet, will help manage the household appliances, acting as a remote control, replace the crib, you can quickly edit a document Word, when not near a computer, it could even measure the volume and distance. Surprising, because the owner of Palma is available just less than 30 thousand names of third party software.

Family of operating systems, Symbian

Symbian operating system today, quite successfully compete with the platform Windows Mobile. On the side of a big Symbian friendliness untrained technical users. Symbian operating system is divided into two groups: the first, developed by Nokia, called the Series 60 (as well as additional options - S80 and S90), the second - version for UIQ smartphones with touch screen and is used by SonyEricsson. The family of Series 60 - a platform based on Symbian OS and is designed for mobile phones. This platform was developed by Nokia and is used in its smartphones, as this platform is used Lenovo, LG, Samsung and Panasonic. Series 60 mobile platform is divided into editorial (Editions), depending on the version. Each edition may in turn have a set of add-ons (Feature Pack). The table below shows the different editions Series 60.

Part I - The mobile operating system "width =" 176 "height =" 208 "/>

Here is the screen smartphone with Symbian Series 60

A distinctive feature of the Series 60 Platform is its multimedia focus and maximum functionality of the phone - you can not even think about the fact that the phone has an operating system. Already in the standard package are excellent editors for photographs and videos, provides not only the Real Player, but also the Flash Player for playing Flash-rollers (WM is being implemented in a third-party program). Additional software is written using a SDK (Software Development Kit) - a set of tools for software development (libraries, documentation, the emulator operating system for PCs), so has a very high stability and compatibility with the platform. All Programs for Series 60 are written using programming languages ​​C + + and Java MIDP. To install the device software C + + files are packaged in SIS, written in Java - in a JAR file and JAD. Installation of SIS-applications for Series 60 3 Edition complicated system of signature programs (need to ensure greater stability). Symbian, however, still lacks the scalability and nadstraivaemostyu as Windows Mobile, making it the most stable platform. An added bonus of the S60 platform is a huge variety of games written specifically for her. This situation arose due to the well-known game smartphone, Nokia N-Gage, based on the Series 60. With all these features, the S60 has won great popularity among the majority of users opting for a smartphone. Series 80 Other Symbian this branch - the Series 80 platform is not much different from the S60, it is used on a limited number of devices - business communicators Nokia 9xxx series (9300, 9500).

Nokia 9300 Communicator

A wide screen high resolution and some specific business functions (work with e-mail, for example), all management is carried out with the keyboard (two of them: QWERTY and numeric). Form-factor device - side flip, causing the device in the unfolded form resembles mikronoutbuk, and folded - hypertrophic phone. Series 90 - the main platform for touch-screen devices from Nokia - this is smartphone 7710.

Nokia 7710

The difference is slightly redesigned user interface and operating system support for touch screen (usually with a resolution of 640x200 pixels). S60 Touch - the newly announced platform. On this platform, there is little information, but we know that in the S60 Touch will be exercised control over the fingers (touch and movement of fingers across the screen) while maintaining control stylus.

Part I - The mobile operating system "width =" 450 "height =" 253 "/>

Screenshot from the video that demonstrates the capabilities of the platform S60 Touch

The original is the fact that according to some reports, S60 Touch will support the tactile feedback - that is, every action you'll not only see but feel. The family of Symbian UIQ. Generation operating systems UIQ (User Interface Quartz) is designed for smartphones with a touchscreen and differs from the S60 for the most part is a graphical environment. This platform is used on smartphones Sony Ericsson, the version currently in use - UIQ 3.0, which is based on Symbian 9.1. Feature of the construction vehicles P9xx series on this platform is the availability of flip - flip the keyboard, the closing of the screen while your device is a smartphone, because the touch pad screen is turned off. Opening the flip includes touch screen capabilities and the phone becomes a full smartphone with touch screen. Supports resolution of 320x240. Machines M and W series are not flip and look like ordinary communicators with a large screen.

Sony Ericsson P990i

Sony Ericsson P1i

Feature of the UIQ 3.0 platform is a large set of software and applications installed on the smartphone manufacturer. In fact, here is everything you need for work.

• Browser Opera 8.0
• RSS-reader (internet news)
• image viewer (viewing and simple editing of photos)
• Sound Recorder (sound recording)
• Quick Office (P990i)
• PDF + (P990i reader PDF)
• Notes (notes)
• Tasks (Task Manager)
• Business Card Scanner (scanner cards, uses the built-in camera, but does not support the Russian language)
• Media Player (media player)
• E-mail Client (work email)
• MusicDJ (creation and editing of MIDI ringtones)
• Calendar (calendar-organizer)
• File Manager (working with files and programs)
• Calculator
• Unit Converter
• Timer
• Stopwatch
• World Clock

Although many of the necessary software installed, they will last only for the first time, and then still have to seek third-party software. And here are manifested major flaws Symbian UIQ, firstly, the small number of programs for this platform and they are mostly paid. Therefore UIQ is designed for those who are not on a particular desire to install applications on your phone - the standard software is made perfectly, but with the scalability problem. Secondly, the platform has stability problems, the new firmware, of course, the correct "wet", but before full stability is still far. Third, there are very weak customizable interface, you can just change the color and shape buttons. Although the possibility of changing the interface is reserved for mobile operators, which have been slow to take advantage of this opportunity. Fourth, SonyEricsson smartphones will only support memory cards Memory Stick, which is not so attractive in price as a competing format SD. In general, Sony is again on its own path.

Separately and original. Mac OS X and iPhone

On everyone's lips, many in the head. Probably many of you have or want to become a "victim" of aggressive marketing by buying today a cult device iPhone from Apple. Sales staff have started in America, July 29, 2007, and the iPhone was tied to one of the cellular operators in the U.S., making it impossible for the phone to other countries. Today, this binding is not due to various tricks, unlock the device. IPhone is based on a special version of Mac OS X, while the interface is adapted for use with your fingers. This innovation was the main "trick" the phone.

iPhone

Feature of the device is a large touch screen, which occupies almost the entire front panel and only one key, all management is done by touch and move your finger across the screen which makes it a smartphone, as it were alive. Today, programs for the smartphone from Apple is almost there, and the Platform SDK has not yet made public, so third-party programs can not be expected. Although, of course, the potential of the device is very high. The smartphone is based on the ARM processor, 620 MHz, screen resolution of 480x320, supported GSM850/900/1800/1900, Wi-Fi, Bluetooth 2.0 + EDR, EDGE, 2MP camera, Li-Ion Battery 8:00 razgovora/250 hours of standby, sizes 115h61h11, 5 mm, weight - 135 g. Standard functionality includes basic phone features.

• Calls, conference calls, no voice control, the main feature - visual voicemail, which works with U.S. carriers, you can manage voice mail messages directly into the phone interface.
• SMS is implemented in the form of dialogue.
• Ring tones are sold in the iTunes Store, in the normal ringing is not provided, but will work when using third-party software.
• Multimedia player like that in the iPod, but is able to much more, and large screen allows you to watch movies with high quality.
• Internet is possible thanks to EDGE and Wi-Fi, as well as built-in browser Safari. There is no technology Flash, however, is the fastest browser among all mobile devices.
• Operating System Mac OS offers in the future possibilities of easy porting of programs designed for the Macintosh on the iPhone. Perhaps then we will get one of the most successful communicators, but so far it's only plans for the future.

Some lesser-known operating systems

Besides the already described by us today, operating systems for mobile assistants, there are lesser-known operating system, for example, Linux or Blackberry. Linux - used PDA from Sharp. This model of Zaurus, little known here in Russia. Of course, this is not a full Linux. Yes, I use the kernel Linux, but here's a shell is quite another and to the compatibility with the "big» Linux it away.

Sharp Zaurus SL-C3100

Sharp used the shell is called Qtopia. The second feature of the operating system from Sharp is the simplicity of the interface and work (unlike the desktop version of Linux), so do not be an expert to learn the "Zavriev. In general, the platform is very popular in Asia, in Russia we spread a little, because of little interest, except for tehnomanyakov who are not averse to play around with different techniques, explore new possibilities. Blackberry - Smartphone series, produced by Canadian company RIM (Research in Motion). The company was able to offer its original concept of mobile devices that have become popular overseas. Blackberry is a platform for wireless communications in cellular networks, which allows instant access to the Internet, e-mail (including a secure protocol Push Mail) and other communications.

RIM Blackberry 8820

Classic Blackberry endowed convenient QWERTY-keyboard and perfectly suitable for mobile operation interface. This is the main components of success of these smart phones, especially among corporate users. As for Russia, while only the MTS and Beeline signed an agreement with the RIM Blackberry platform to implement in our country as a whole, these smartphones we have practically never occur.

Conclusion

In conclusion, we note that this article spoke only on the tip of the iceberg, because the review of each operating system can take an entire book, here represented the quintessence of opening the veil of secrecy on newcomers, thinking about moving to a smart car. In the next article we will consider in detail the various PDAs, smart phones, communicators and navigators, their differences, form factors and features. In the meantime, let's sum up today's paper. Of course, choose your device to you, we just try to help. Below is a table with the main features of each OS. The authors, translation:
