Best UI

The best UI that I have used is Itouch4 8g produced by Apple Inc. Everyone must be a fans of Apple.I am so impressed.

Pros

(1) It supports multitasks. It is a very important improvement since Itouch3. Multitask means that users can make any program run in the background. Suppost that when you are talking with friends via MSN, you hope to check your email. When you switch back, MSN is still running. For itouch3, it was impossible and only could be implemented by some third party programs.

(2) It provides cameras and build-in microphone. Can you imagine that such a good machine doesn't have a microphone and cameras? Before itouch4, there were none. Back camera can help take photos, and front camera and build-in microphone can help make visual communication with friends.

(3) I like it mainly because of its "touch" function. I like the feeling that if you want something, just touch it. I am kind of tired to traditional input devices, like keyboard or mouse. Also, itouch4 supports multitouch. I can use my two fingers to zoom in or out pictures books.

(4) It supports a lot of software, like gmail, msn, twitter, and etc. Almost all routine software in my laptop have their editions of itouch4. So itouch4 is like a multi-touch micro-laptop.

Cons

Actually, I am 100% satisfied with itouch4. It is really hard for me to find some cons. It would be better to add user manuals for novices in the mainframe. Multi-touch system is pretty different with traditional systems. When I first used itouch product, it really cost me half an hour to find how to delete a program.
