At present, the PDA market is dominated by the Pilot series. Even with a very high market share, you can't be complacent. 3 COM has independently turned the PDA department into a handheld computing company, hoping that a company can concentrate on mastering this ever-changing information market. Generation after generation of the pilot model, so that this series of PDA has more capacity, fonts and a cooler appearance. After adding the infrared port, it also takes into account the trend that there is no online network in the future.
In the rapidly changing era of high-tech competition, one is the largest software manufacturer, and the other is the PDA leader with current market share. More and more manufacturers are eager to get ahead. At present, no one can say who will win this wave of PDA system competition. Perhaps, whoever is most in line with the future trend will have a better chance!
Wireless transmission will also be the future direction, that is, no matter where the user is, as long as wireless communication is combined with the technology without online network, PDA can run without worry. In addition, PDA will be developed, and the storage capacity and processing process of the system will be handed over to the remote server, which also shows that PDA will become smaller in the future, because some hardware devices are missing, and the access operation mode of the remote server will not cause the loss of its own data even if PDA is lost.
Later, PDA cooperated with telecom operators and financial operators to develop PDA into e-finance. Its functions include stock market, financial management, personal paging, assistant secretary, news center, life information, amusement park, member world and so on. Today, this PDA is the king of messengers and a miracle machine in the market. Their convenient design has been recognized by stock family, which has once again opened up the market for PDA.
By inserting a card through GSM, PDA can be turned into a mobile phone, as well as regional network cards, wireless network cards and even Bluetooth network cards. These networking devices will make the expansion function of PDA more powerful, and of course, the application of PDA will be more extensive.
PDA (Personal Digital Assistant) will bring great convenience to mankind now and in the future. With the advent of the multimedia digital era, there will be no wired and wireless technologies such as ia (information appliances), broadband, online networking and wireless transmission in the 3G era, and technology and life will never be separated.
The most attractive thing about PDA is its endless development in the future. Let's imagine how convenient it would be and how much space we would save if all the functions of desktop computers could be used on PDA now. I believe that PDA will be one of the most potential products when the personal computer era comes.
At present, there are two main types of PDA:
(1) Pure PDA: This kind is mainly divided into Palm system and WinCE system. WinCE system is the mainstream at present. Originally, I used Palm, but now I think it is very useful to switch to WinCE. If you want to use satellite navigation, this PDA usually has its own Bluetooth interface and then connects to the Bluetooth GPS.
(2) Many companies have built-in GPS PDAs, such as ASUS, Acer and Hewlett-Packard. It will be more expensive, but with built-in GPS, you won't get lost when you go out. I am Acer N35 myself. Although it is not a very strong machine, it is cheap and easy to use.
(3) PDA based on GPS. The main appeal of PDA with built-in GPS mentioned above is PDA, but PDA with GPS is aimed at people who don't need PDA function very much, but just want to use GPS function simply. The function of PDA itself is not strong, but its satellite navigation is superior to other PDA in satellite accuracy and map details, and its map program is not the mainstream PaPaGO of PDA.
(1) (2) They are basically PDA, so the functional requirements are very close. Now the mainstream specifications are Bluetooth, no online network and so on. See if you need it. In addition, PDA can install software according to its own needs after buying it back. Let me share my PDA purpose for your reference: 1. Play video games (Empire of the Century, New Cards, Bubble Dragon, GBA).
