Despite two years of winter for Pocket PC industry the morale plummeted, and even SONY, JVC, SHARP and other Pocket PC main Japanese manufacturers announced its withdrawal from the U.S. market, limited product launch in Japan in order to reduce the cost of sales to control the damage, but can not deny that the Pocket PC has been showing a touch of trend to recovery. According to IDC's market research report, the third quarter of 2004, Pocket PC shipments grew 13.6% over the same period last year, despite the deadline this year is not related to sales results, but the handheld computer market in 2004 sales will be excellent already in the past two years is an indisputable fact. Part of the strong competitors will remain out of Pocket PC manufacturers with greater opportunities for marketing, but the fact that some manufacturers will put more pressure on. For Pocket PC is not only facing the problem how to make existing products, but also to deal with challenges from smart phones.
From the "Newton" came the beginning, Pocket PC PIM on the ability for users to provide the main function, though gradually with the subsequent development of music and video players and other multimedia features, but has not met the expectations of the "Pocket PC" in the requirements; the smart phone is different, due to differences in consumption concept, people can call like that phone, so smart phones is seen as a progress beyond the traditional mobile phone, so when running multimedia applications, ease of use defects and performance for the lack of tolerance zone was too, so "Pocket PC will be replaced by smart phones" are growing louder.
Pocket PC besieged on all sides because it is a Pocket PC replacement performance at stake, such as low resolution screen is difficult to show more useful information, processor, graphics chip, poor performance, it is difficult to bear the pressure generated by advanced applications, etc., not 1 and foot. But we think it is too early to Pocket PC's death penalty because it has the advantages of the present without any kind of products can be replaced: a relatively mobile class competitors it has better ease of use and functional scalability, has been in the market have appeared on mobile phones, GPS-enabled handhelds is a good evidence. Compared with the laptop is fully shown its advantages of small size, users can carry it in the pocket, and can well handle e-mail, work documents, and some entertainment tasks, so that the handheld computer as a personal information interactive platform more good than harm.
Obviously, the Pocket PC handheld devices you want to re-Xiong Qi must be in size, performance on the show more character, and which requires the joint efforts of the other vendors ... ...

Sharp tools make good his tools
As with PC, Pocket PC has the computing, storage, display and other components, and with the popularity of wireless networks, wireless modules will become one of their standard, so Palm would like to improve the performance, in essence, can only send hope to control the relevant equipment manufacturers to speed up production efforts.
Intel, Samsung, TI 3 processor for handheld devices The main vendor market share and product performance in view of Intel's XScale family of production is undoubtedly the most advantage of the current products, the current mainstream PXA 27X series processors will not only maintain the maximum operating frequency of the advantages, but also Wireless MMX instruction set, SpeedStep capabilities to some extent mitigated the increase in performance and power conflicts. In this test situation, where the PXA27x processor using the product or solution in terms of compressed video files, and data query performance of all aspects of product than in the past have largely improved.
The test products in three product uses Samsung S3C24x0 processor, and uses Intel processors compared to, though not with automatic frequency adjustment and Wireless MMX functions, but the performance difference with the same frequency XScal processor but not the poor, and energy performance is quite good. 667MHz Samsung S3C24 family of products with the emergence of more mainstream products will be used Samsung processors.
Pocket PC's graphics performance has been unsatisfactory, even in mid-2004 most of the products on the market in video playback for generations could only Yikao CPU calculus, so not only high-quality video playback slow, poor picture quality, but also consume large; 2D quality like this, see 3D performance is more out of the question. View of the application of the pressure, Intel, ATi, nVIDA are suitable for introduction of the new Pocket PC to use the graphics chip, the second part in the test of HP hx4700 and the Dell AXIM X50v on the ATi Imageon 3220 respectively and the Intel 2700G graphics chip; nVIDIA graphics on mobile phones now main attack area, but through the acquisition of MediaQ already have an abundance of technical accumulation, therefore, believed that the year will be full GoForce series appeared in the Pocket PC.
Of course, users are more realistic is fully introduced into Pocket PC VGA screen, use the product with four times the resolution of QVGA resolution, the effective display area, so that handheld computers browse documents, pictures can not only see more, but IE supports VGA resolution, the resolution is one, so visit the website of the visual effects more comfortable.
As an extension of personal computing devices, with full network connectivity will become very important, and interact with other types of terminals will no longer be limited to USB or infrared transmission, Bluetooth, WLAN and other high-speed wireless modules will become a Pocket PC equipment module. I am pleased that the products involved in this test has Bluetooth as a standard configuration, or even more, the HP iPAQ rx3715 features Bluetooth 1.2 module, due to cost reasons, WLAN module basically only in the high-end products, but considering the integration WLAN, Bluetooth Combo module has already begun and equipment products, the WLAN module is likely within the next year in the popularity of handheld computers.

Introduce new applications for the king
Traditional PIM, clear audio playback and the like functional Pocket PC application is no longer the key, how use of the performance benefits derived from other types of applications? Some manufacturers have chosen "Quxianjiuguo" strategy, in the handheld computer with integrated GPS module, GPS in the field trying to open a new personal breakthrough. Another part of manufacturers and products on the secondary development, such as support for Pocket PC video output, and multi-media video on demand service providers co-operation; Huanyou part of manufacturers to use the crazy upgrading hardware Xingneng such a "high-handed" approach won Users favor - such as Dell AXIM X50v can allow users to experience 3D games between the hands of pleasure.
Of course, simply to hardware-based enthusiasm to mobilize the user is not reasonable, because the economic conditions, most users use a pocket computer Zhouqi a long, Bukenengxiang as frequently as PC accessories upgrades, so Zai existing Qingkuang Under the application for the Pocket PC to provide more solutions for most manufacturers consider. For example, the rx3715 on HP's "multi-media mobile companion" concept, in the provision of audio and video features at the same time part of the media center into which the concept of using the machine comes with the wireless transmission interface, users can conduct remote control home appliances, and able to network multimedia files on the PC to control the first time introduced the concept of information appliances Pocket PC.
With the wireless network further, application-based wireless networks are also beginning to start, such as Mitac has introduced the use of the concept of smart phones to watch TV on video applications for handheld devices presents a viable case, though now offers narrowband Video quality was not satisfactory, but now mainstream products have a high-quality video playback capabilities, but also with IEEE802.11b wireless network coverage increases, accompanied not be long before the arrival of cinema.
To enable users to launch the Pocket PC 2004 processor, graphics, and understand overall performance, "PC" planned laboratory evaluation compared Zheci Pocket PC themes, we recruited from the five major Pocket PC manufacturers 8 products for testing. Because the products involved in testing both the most high-end products, including products and economic mainstream products, so can provide you with the purchase of a more comprehensive reference.

Performance Test - Pocket PC
To ensure that the Pocket PC has the same software environment, the testing involved before we started the tough test products to ensure that no possible impact on the test procedure exists. To ensure that performance is maximized, we will test all of the software are installed in the machine memory, and is cleared before the test and Pocket PC memory resident program. Before the battery performance testing, In addition to closing the application of relevant procedures will be adjusted to the brightness of backlight brightness to abolish the automatic shut down of time limits and shut down all wireless transmission equipment, and a processor running faster Sheding for the Quan Su (because some of the products by Samsung processor does not have the automatic frequency adjustment function), making handheld computers to allow the battery within the scope of the longest battery life. As the video test file large memory on the machine may cause the system memory, so when we use the SD card test as a host medium.
Be noted that because of this test include Palm, PPC product of two camps, so there is not much comparable benchmark, if you want to test scores for the purchase of reference, we recommend that you battery life and video playback capabilities As a reference, because the main application of pressure at this stage still from video playback, while the standby time of handheld products that both are important to any camp.
Benchmark
Windows Mobile
We use SpbBenchmark, VOBenchmark two software testing with Windows Mobile Pocket PC operating system. One SpbBenchmark is Spb Software developed its own set of free software for application testing, the test included files, graphics, CPU, application, synthesis, and battery test six. One document properties include file / read-write, directory creation, data query sub-test items, a good simulation of the Pocket PC application constitutes a file number and size of a small environmental characteristics. It's CPU tests include extracting file, compressed graphics two parts, for integer, floating-point two tests, the basic embodiment of the mainstream applications may create pressure on the processor.
VOBenchmark 3.0 is a set of theoretical data analysis focused on the software, its all part of the Pocket PC can be analyzed in detail. CPU test part of which includes floating point, integer performance of the two tests that can objectively reflect the processor's specific performance index; its graphics into a static test pattern generation capability (Filled) and display speed (Bitmap) two aspects. Pocket PC application performance testing of one of the main aspects of the management efficiency in the internal memory, and the software can allocate memory, fill test and the memory block (file sectors) movement testing; is worth mentioning that VOBenchmark specifically with the GAPI FPS Test (GameAPI) test kits used to test Direct Video performance (that is, the fastest running speed in some games), is a comprehensive measure of Pocket PC's integer, floating point and 3D performance of the test suite.
Palm OS
We use the Benchmark 2.0 and PalmBenchmark both Palm OS operating system software on the machine used for testing. One Benchmark 2.0 is through intensive operations on the processor and memory bus efficiency test, the test results to Palm 鈪?e / 鈪?xe performance as a benchmark of 100% participation in testing the product in the scores based on weighted calculation to get the final test results. The PalmBenchmark is PC Professionel palm production models for testing a data-processing, graphics generation and file transfer performance of the software, refer to score 10 points.
Test video
Windows Mobile
We use Betaplayer 0.096 for PocketPC video playback test, taking into account the participation in this test Pocket PC with the performance differences, we used two different sizes of video test, in addition to minimize the additional overhead, We closed the sound output.
Additional explanation is that, Betaplayer graphics core will be selected for different decoding methods such as using the Intel 2700G decode X50v, hx4700 using ATi Imageon, and we have no choice in the testing and integrated decoders, but the selection is suitable for testing machines and implementation of efficient encoders.
Palm OS
Palm handheld computers, we test the video playback test used MMPlayer0.2.13, but with the Pocket PC using the same test file, but due to a software software, we were unable to completely turn off audio output, so some effect on speed .
Power endurance capacity test
Windows Mobile
We use the Windows Mobile operating system by SpbBenchmark test products, the software can truly simulate the use of handheld computers, which by running the script to switch, the implementation of the application, so that system to produce affordable, close to the real usage.
Palm OS
BatteryTIME not fully reflect the practical application of the load when superimposed by a variety of performance differences emerged, but can simulate the battery in the best of the power decay rate, taking into account the test must have repeatability, we still use the software for battery testing.
In addition to the benchmark tests, taking into account the integration of handheld itself is very limited memory capacity, especially in the frequent use of multimedia features user is stretched, many users have acquired a piece for the Pocket PC memory card, so we read his SD memory card performance were also tested.

Asus MyPal A730
A730's size small, 117.5 脳 72.8 脳 16.9 (mm) part of the volume and not significantly less than smart phones, handheld computers also called in the small, even more valuable is that this is a with a SD / CF Double slot, 3.7 inch screen of the Pocket PC.
In the configuration, A730 uses 520MHz Intel XScale PXA270 processor, Built-in 64MB Flash ROM and 64MB SDRAM (actual free space is 45MB), and built in Bluetooth and infrared modules. Of course, if you need more memory, and WLAN module support, you can buy an enhanced version of A730 A730W. It is worth mentioning that, A730's Flash ROM provides users with 19MB of backup space, with the A730 to provide a file backup tool for users to easily back up critical data, even if you do not have extra memory cards do not have to worry about backup space .
A730 with a 1.3 million pixel camera and comes with flash, self-timer mirror and other devices, and users can adjust a variety of shooting modes, effects, brightness, contrast and other functions, the use of a high degree of freedom. With built-in image editing and management software, you can entertain themselves very quickly to complete some work.
In the performance test run, A730's performance may be acceptable, but A730 to users of available memory space is smaller (only 45MB) and will start after the system occupy about 13MB of memory space, so users can actually use of space is only 32MB, so in the presence of system background task will affect the normal use, we recommend to buy A730's user must purchase an additional memory card.

Dell AXIM X50v
As Dell's flagship product, X50v configuration did not disappoint, it uses a 3.7-inch VGA resolution display, the processor uses Intel 624MHz XScale PXA270, its integrated 128MB FlashRom and 64MB SDRAM (user available space sum 139MB) ; its network, extension is also very comprehensive, not only the IEEE 802.11b wireless LAN and Bluetooth, infrared module also provides a CF / SD expansion slot of two types, for use when the user extensions.
Memory card slot is more surprising is that it's graphics system, X50v with the Intel 2700G graphics core, we know that 2700G is a memory-chip integrated graphics chips, but vendors for additional information that the X50v is installed 16MB memory to meet its better to play a 3D feature.
X50v comes with the software very practical, it provides a wireless network management tool that can display signal strength, encryption options, Wi-Fi certification and registration options, allowing users on the current state of well known practical wireless network. In addition, to allow users to fully experience the thrill of handheld 3D, X50v also bundled with Stuntcar Extreme (X50v special edition for the 2700G-optimized) and Enigmo two games. It is worth mentioning that the first integrated Windows Media Player 10 Mobile for Pocket PC, so you can provide a greater variety of multimedia services, you can not only enjoy the local music, video, and can display pictures or use Windows Media Digital Rights Management 10.0 access audio and video media library, enjoy a more abundant resource.
In the test run, X50v processor performance is satisfactory, but the graphics test scores low, but this does not indicate its weak performance, but because the test program can not currently make full use of 2700G more advanced decoder. As the battery capacity is low, therefore the standby time is not ideal X50, we tested the time is about 2 hours and 40 minutes, so we recommend users to buy X50v to buy a customized specifically for use with 2200mAh battery.
As the market's first 3D acceleration with the Pocket PC, we believe that X50v is a product worth buying, its integrated value is not inferior to other Pocket PCs with VGA screens, if looking at the Pocket PC to play some 3D game, then this is your best choice at present.

HP iPAQ hx4700
hx4700 with a 4-inch VGA display, this piece of screen in terms of color reproduction or brightness, viewing angle on the performance of all people quite satisfied, although the overall color temperature of some warm, but it must be admitted that this was the best we have seen Pocket PC screen. hx4700 2MB of video memory with the set of ATi Imageon 3220 graphics chip as the GPU, but before Toshiba e800 also uses the graphics chip, so a lot of software is optimized for it, used in conjunction with various types of software are very stable.
hx4700 other high profile, it also has WLAN, Bluetooth communication module, and the best use of the current performance of the processor - 624MHz XScale PXA270 processor and built-in 128MB ROM and 64MB RAM (the actual available space for users to 135MB); addition, to ensure users have enough room for expansion, hx4700 also provides SD / CF expansion slots to meet the needs of two.
hx4700 with Windows Mobile 2003 SE operating system software comes with its very rich, in addition to iTask, iPaq Wireless utility, Image Zone, HP Mobile Printing and other self-developed program, but also bundled with a very powerful PIM management procedures-Pocket Informant 5, even if you are a first-time handheld computer novice, do not install any software can hx4700 all the functions on its head.
And the same, the Dell X50v 634MHz processor, compared, hx4700 in the CPU, memory card benchmark tests have certain advantages. Although the hx4700 to meet the current high-quality video playback, and picture quality good, but simply in the video broadcast speed test hx4700 still exposed Imageon 3220 chip performance issues behind the 2700G. Should be sure that the hx4700's battery life, more than 6 hours of battery life capability of this test, though not the most outstanding products, but also quite compelling.

palmOne Tungsten T5
Tungsten T5 is the first use of Flash ROM instead of the traditional RAM and integrated 256MB ROM first handheld computer, as Flash ROM will not lose data even if power-down, so it was given the functions of mobile storage - built-in software user can choose whether to TT5 as a flash disk. In addition to user-friendly management of large-capacity memory, TT5 first introduced the document management capabilities, users can manage files using the tree list, so use more convenient.
TT5 data line interface with a new design, data lines and power lines are independent, you can go out in the power cord, data line, choose one, because TT5 with USB port to support IR sync and charge capabilities. Also worth mentioning is that through the new interface, TT5 base can be achieved with the related video, audio output function, so in the purchase of accessories, TT5 can provide you with a video presentation platform.
Tungsten T5 Palm OS v5.4.5 operating system using its standard Documents ToGo, Blazer, VersaMail, RealOne and other software applications to meet basic daily needs. It is worth mentioning is that it provides a very handy feature, if the hold down the "Desktop" icon will appear before running off five "background", this is the Plam OS provides a quick way to start the application Although not really the background, but with the background of Windows, the effect of the implementation of already very close.
In the test run TT5's battery life is quite good, the battery performance test that can continuously run for 5 hours; in actual use if the backlight set to medium it can be maintained for a week of daily use and no charge. Of course, the drawbacks of using the Flash ROM is also reflected in testing, due to Flash ROM and RAM speed falls far short, so data access (especially large-scale data access) to be inferior to the machine using SDRAM, the most direct ways to achieve is that we restart the machinery had to wait quite a long time to enter the user interface.
