Ipad is a mobile device, between a computer and a mobile phone. Compared with mobile phones, the screen is mainly large, so it looks more enjoyable. At the same time, it is more convenient to read documents and consult materials on a big screen, so it is more inclined to computers than mobile phones. But Apple's ios system can only install its own software, not as much as our commonly used windows software. Many large programs on the computer, such as photoshop, design software, document editing software, etc., are more refreshing and convenient to use on the computer. Ipad is suitable for artists who often play games and watch movies online, because ios software resources are quite rich and there are many high-quality applications. There is also a business person who needs to send and receive emails and check information frequently. If the computer is turned on slowly (of course, the speed of the recently emerging ultrabook has been obviously improved), it is impossible for business people to turn on the computer and then turn it off just to read an email. If you have a tablet computer, you don't have to turn it off, so you have an advantage in this respect. Simply put, it is more enjoyable than the mobile phone screen, lighter than the computer, faster to start, and convenient to carry and use. At present, Android and ios tablets are of this nature. In the future, except for the tablet of windows operating system, it will be the same operating system as ordinary computers, so it will be similar to ordinary computers.
