Topic for May 15 -- What a mobile device can do and a desktop cannot do, and vice versa?

Mobile over desktop/laptop

mobility: the first thing is mobile devices are mobile. You can bring it anywhere, use it anywhere at any occurences. As an additional benefit mobile devices happen to be able report their position and orientation. You will be able to know where you are and which direction you are facing even when your biological brain cannot tell. The term of mobility not only refers to that you can use your devices on bus or on the beach, it also means that you can browse internet while lying down on bed, while running on treadmill. You don't have to sit straight and face a screen.

private: because the mobile devices have to be made small enough to be portable, there is physical limitation of its size. This limitation sometimes becomes an advantage -- the screen is so small that the guy beside you cannot see anything while you are watching a video on your mobile phone. It makes the mobile device a very personal device that you can keep fair amount of privacy.

identity: because the device is small, portable and private, people tend to put it into their pockets, and bring it wherever they are. Mobile devices become electroical identity of humans. You use it as a ID, you use it to make payment, you use it as a bus pass etc.

Convergence of multiple electronical devices: we will see more and more digital devices attaching to our body anywhere at any time.


Desktop/laptop over mobile: the conclusion is immobile devices as desktop/laptop will lose its publicity, as long as mobile devices are powerful enough to satisfy our every growing everyday needs, and the UI of mobile devices is able to easily switch between private and public mode.
