It is more vague to "handheld" and PDA definitions. However, a definition of the highest recognition is that the handheld computer refers to an open Pocket PC (PPC) and PALM for the hand-held personal information assistant for the operating system, and the PDA generally refers to a simple personal number of closed operating systems. Assistant, such as the previous business, the product, such as the express translation.
The former has attracted the participation of countless programming masters around the world, and even very professional large software companies have a rich software. And that these software make PPC and PALM have infinite possibilities and very strong extensibility. The latter (PDA) is not extended in the function and software due to the closure of the operating system, without the participation of third-party software authors. Generally only as electronic dictionaries and some simple personal information management tools. In addition, since the built-in memory of these PDA products is less pitiful, they do not have expansion slots, which make them narrow. However, here should mention a particular product, more representative is the PDA7000 and PDA8000 of the Zhanda network, 218 of Zen, and TCL EJOY I, II, etc.
Within a certain price range, they joined the MP3 function and large-capacity flash on the basis of a general PDA hardware, and easily achieved complex and recording due to the addition of MP3, so that this grade is very practical. With multimedia features. However, due to the unopened system of the system, the built-in software built-in software cannot meet more users' diversified needs; the screen generally uses a short-term low-resolution monochrome screen, etc., but the influence of such products is always Less than a level that can be selected by the consumer.
In the year, PPC and Palm continued to improve the product hardware configuration and constantly reducing prices, and making competitiveness more and more stronger, there is a general situation!
There may be friends to say, the handheld computer is limited due to the volume limit, the screen area is too limited, and the overall data processing level is limited, how can it be with strong, there is a laptop configured as a desktop, and the laptop configured as parallelism. Why don't you buy a laptop directly to buy such a little, you can only play the equipment that can play a small game? This kind of saying is good, but it ignores a very important point, even if it is portable. Pocket is generally slightly larger than the adult palm, and can be easily operated, and the weight is generally below 150g, (below is currently the weight data of some mainstream handheld: 620: about 141 grams (including battery and Stylus, 2210: 144.2 grams, 1940: 124 grams (including battery), 336: 110 grams, 71: 150 grams, TT: 157 gram, TE: 131 grams, T3: 156 grams) Computer ratio with huge and bulky laptop Get up, the palm computer is undoubtedly a thinning.
This is where it is when it is, a handheld computer can carry it with you, use anytime, anywhere. And the laptop is in this point, no matter how it is better. What's more, the current development speed of digital products is really a new day, and the performance improvement of the handheld computer is getting faster. Imagine who would think that the CPU of such a small handheld device can actually achieve smooth video playback up to 400M Hz and can achieve smooth video on a PDA size machine? Who can imagine how the handheld computer will be the level? I think the powerful portability advantage of the handheld is enough to make up for some of its shortcomings and the powerful performance of the laptop also masks the drawback of inconvenience. The author is in recent years in www.mypda.com.cn, often seeing netizens asked some questions such as what the hand can do, it is in nature with the laptop and general PDA. s difference? I'm here, so I have the following text. Due to these factors mentioned above, this paper generally does not compare with the PDA more than the laptop.
The main reason for purchasing the handheld computer:
Learning function
When it comes to the learning function, the first thing to mention is the dictionary function. Although there are many PDAs, including Wenqu Star, Express translation, celebrities, etc., all sell points in the dictionary and emphasize that the dictionary can be expanded through the network, in fact, it is really used to find a limited limiter. First of all, the built-in memory of this type of PDA is very poor, and then the user is difficult to load the dictionary you want. The PPC and Palm have a variety of third-party software due to the openness of the system. Take the most classic dictionary on the PPC (this is still a free software), now there is a true authoritative Oxford English-Chinese Double Phase Library, Webster English English Latex, Cobuild Collines English English Latex, 21st Century English-Chinese Han Yingxin, can also fascinate Chinese teachers' senior Chinese big dictionary, international standard Chinese characters (Simplified) and Chinese idiom dictionary, or even English dictionaries, as long as you need, and you have you have With a large expansion card, you can put these dictionaries, read anytime, anywhere. In addition to MDICT, there is more dictionary that meets different users of different needs. If there is a "pocket genius", "pocket genius", which can vocal, and "more translated". In addition to these authoritative dictionary (Oxford, Webster, and Chinese Dictionary, Palm), Palm, the English and Chinese Chinese-English Word Library, and the popularity of the world, etc. How do the PDAs have the built-in curing small dictionary with the palm computers? Moreover, there are more exciting to meet a variety of learning software that meets a variety of different needs.
In addition to the dictionary, I learned, of course, I still have to learn notes. Hanwang handwriting (recognition speed and identification rate is very good) across the PPC, the English input method is very good, and the English input method has a Calligrapher who is never in any PC English handwriting software. General pleasant feelings), there is a generation of classic Giraffe on Palm, and users can also install more handwritten software such as Mengyi, monsters, plum blossoms, etc. The general PDA is generally identified by the same speed and identification rate due to various relationships (very likely copyright is the most important reason). English is even more PDA to provide handwritten input. Think about the pain of the fine virtual keyboard with the detailed pen, don't say that the speed is can't stand up, and the spelling of words is a big problem that is a headache. (Calligrapher can have automatic correction spelling features). In this way, it is a relaxed thing to make a Chinese notes and English notes on the palm computer. The author has always used the ASUS 620 as a notebook notes, and it is very convenient.
Of course, it is very important to read it. There is a detailed narrative in the "PPC Usage Experience - ASUS 620", which is no longer repeated here. Plus the current handheld computer, whether it is PPC or Palm, basically all have already used 650,000 colors of true color screens, no matter what light, it can achieve a pretty good reading effect, 岂 是 单 色 屏 背What can I feel better than reading? All kinds of books on the Internet should have, there is a handheld computer, you can take your favorite books with you.
Entertainment function
In addition to powerful data processing functions, PC has a very charming entertainment. Watching movies, playing games, listening to music online is a small dish. So what is this little handheld computer? The result may be enough to surprise you.
Watching a movie on a device that is slightly larger than the palm of the machine may just stay in the science fiction or 007 series movies to see the scenario? Looking at the 007 James Bundess using the small handheld handheld computer to use the satellite global positioning system to chase the bad egg is special. These new things that have been uncomfortable from high places are now being around us because of the rapid development of digital products. Now the mainstream PPC and Palm have a 400MHz processor that is not a news. It is also very smooth when watching video files. Generally, a 256M expansion card is installed in addition to some of the necessary tool software and personal information, music outside the music, can completely install one and a half-hour movie. Open the handheld computer in a boring journey, play a movie that is hot, but it is very attractive to MM. If you are a busy man, it is too heavy that the laptop is too heavy, then a Bluetooth or WiFi mode network is will definitely help. In fact, with the sharp increase in the number of handheld computers, more and more professional websites, which are specially viewed for the handheld computer, and the content is rich. Imagine with QQ, MSN and your friends on the handheld computer, chatting.
Speaking of entertainment, of course, you have to mention the game. Maybe everyone will often have a need to take a break, play the needs of the game. Of course, this group of game programming is also big! In fact, you don't have to worry about the number of games and wonderfulness. Take the PPC, from a large-scale action game "Ancient Tomb Raidth I", the ancient Tomb Raise I ", to the large-scale instant strategy game" Imperial Age ", and the arcade effect , And let you find the simulated game of the fighter, the stagnation of the stagnation, the smaller to China Chess, Wuzi and Poker, etc., the game on the PPC is almost everything.
Palm is also not inferior. Of course, I have to remember not adding to the game. After all, the game is just a game, can't let the game delay learning.
Because there is a 650,000 color, the handheld can of course be a good photo album that can be carried with you! Thinking about your favorite GF or BF photo with you, let her (he) accompany you at all times, is there a special sweet? Of course, I can take my baby's baby to take it out to a friend to see it. It is also a good idea. Like the ACDSEE of the PC version, the popular viewing software "Action Photo" even has a relatively good picture processing and editing.
You can see the picture, of course, you can watch comics. Are you often looking at rich online comic resources and lamenting only to watch comics in PC? With your handheld, you can enjoy the wonderful comic masterpieces as you want.
What kind of "The Romance of the Three Kingdoms", what "Iron Arms Akong", "Dr. Qin", you can think about it. And you have to do it just copy to your expansion card and then install a small software to watch comics. Is it a bit tempting?
If the above features are just entertainment and pastime, the remote control function of the handheld computer is very practical. Is it a little annoying to watch a few more home appliances? In the case of a cup of tea, it can get rid of it. Let's make a backup with the remote control software of the handheld computer. There are related remote control software on PPC and PALM, in addition to built-in databases, it also provides a very convenient learning function.
As long as you use a simple learning function, you can make a backup on your handheld remote control in a few minutes, you can replace each remote control at any time. Listen is good, in fact, this is just a small function of the palm.
Watching a movie is not a problem, then listening to music is certainly not going down. The mainstream handheld computer product itself is a quite a good MP3 player that can easily achieve completion of the complex function under certain software support. As far as my 620, its sound quality is not better than the vast majority of domestic MP3, and the supported file format is also very comprehensive. Pen screen can also support seven or eight hours. It can be said that the handheld computer is also qualified as a Walkman.
Work tool
In addition to learning and entertainment, what can I do in the work? I think we can't ask a handheld device to be in terms of functionality to the PC. As a tool, the handheld computer helps you use the zero time, always write your inspiration (sometimes a sudden idea can help make you different. You have to do it right away.) . Word, Excel, the most popular office software on these PCs also has the version of the small one of the handheld computer. Although the function cannot be compared to the PC version, it is also enough to cope with the general "small-scale" demand. Because the handwritten input of the handheld is already very mature, editing text on the handheld computer, processing data is very practical. After all, you can't run a PC. In addition to the built-in office software, third-party office software is even more exciting. By Bluetooth or infrared, your handheld computer can easily communicate with your phone. Backup business card book, short message, send, and receive short messages, etc., because there is a handheld computer to get easier. Because after all, the handwritten is more than a few limited buttons in the mobile phone. What is the editing and management of address books and short messages, and the handheld has a powerful function that cannot be comparable. Of course, you can also choose to make the handheld computer and mobile phone on a host, but you have to prepare your Money. Such machines often have 2 times more than the palm host. Perhaps it is not so ideal in the world.
As a device that can be called "computer", third-party software on the handheld computer gives its unlimited vitality. For users who often have data statistics and to conduct scientific calculations, this calculator can a large extent, can replace their original scientific calculator. What is more than one calculator is always a bit uncomfortable with you. On the handheld computer, the user has to do is to start the software and start the software when it is needed.
Since the handheld computer is almost in volume with a general PDA, should you use as a general personal digital assistant?
In addition to the built-in address bookmarks, memory books, notes, notes, schedules, reminders, etc., which can be updated in time and timely updated, and more than those of the handheld computer more than countless personal information management classes. To enhance and compensate in the shortcomings and diversity of these built-in software. On the PPC, a ListPro can get some of such things such as business card management, notepad, write diary, general table processing, etc., and the interface is more human and more convenient. Your life and study can become more stronger, more efficient because of the help of handheld computers. In one sentence, with PDA ratio, personal information management is only stronger. In addition, by expanding, the handheld computer can easily implement DC, camera functions, radio functions, and more. And these can be a little DIY taste according to the user's own needs, is it a bit DIY taste?
Final conclusion
As I said earlier, as a handheld device, it is expected that the handheld computer has the same data processing performance as the PC may be unrealistic. If it can be implemented, it takes time. But in some respects, such as dictionary, learning notes, capture some instant creative inspiration, personal information management, game, etc., the handheld has completely helps you get these things from the PC, let you stay Time or zero time to do. In fact, I am just a very small part of the handheld computer to do things. Remember, all of these features don't do on a huge computer, but in a handheld device that can carry it with you. Think about how much you can help you improve your work efficiency! After all, the palm is light, and it is not necessary to make it like the PC. Using a lot of cost to achieve more and more efficient work, this may be the premise of the handheld computer to survive.
