No matter which format you read, there are several reasons to choose.

First, the screen size, choose the size you think is suitable for reading. Personally, 10. 1 inch reading experience is very good, Samsung and Amazon can toss 7 inches.

Second, the screen material, choosing a transparent screen has a better visual experience than a backlight screen. Apple and Samsung are both made of this material. Samsung's own SPL soft screen color will be more beautiful, and the compromise screen used for ipad is a hard screen with ips. Personally, I think soft screen will be a trend, but technology needs to break through.

Third, reading formats, common formats, such as PDF, Doc, TXT, can be read well on any system, mainly depending on the software, not the system. Apple has its own iBOOK, which can directly download Niu X's books, and computer guidance can also be used. Others are third-party software on ios and andriod, such as GoodReader and IFile, Document, and Microsoft's own Word. But there is a strange trend, that is, after the release of WIn8, a tablet needs to be installed. If the integration of WIn8 and tablet is good enough, which Android and ios should I choose? Why don't China people who are familiar with Win for a long time use the king of PC system?

Fourth, the PDF under CNKI can certainly be viewed, but the strange format of HowNet itself certainly has no software support on the tablet, unless you ask him to make one. As for whether it can be downloaded directly on the tablet, this has something to do with the design of the website and the support of the tablet for the browser. Andriod has never tried to download directly from the web page, and the browser on ios can't actually download directly. Indirect download is ok, but it's annoying if you don't get it. If Win8 comes out, you can play games no matter what you download. I think it is impossible to download HowNet directly to the tablet. This is the simplest and most convenient way to synchronize from the computer to the device.

Fifth, I personally feel that the operation of ipad2 is very smooth. Whether you want to see a PDF or a process document, there are all kinds of messy apps, and 14w can be mined. Of course, there are some such applications on andriod, but there are no free resources on itunes, no jailbreak, and no cracker is willing to crack those charged applications. It's really fun. You'll find it only after using ios. Oh, the system.

Sixth, what else to consider? Before Win8 is integrated with tablet, it is a waste to choose other brands. HP's touchpad still can't stop the ipad2, and Sony, MOTO, Asus and Lenovo all have some fragments of the whole mz. As far as AMZ is rich, it can support the whole cloud board of Niu X. Before Intel boss came out to teach ARM and Nvidia, the chips on the tablet were all floating clouds, and the system went out without washing itself.
