yeah! absolutely!
but you know what? when i wrote this reply, i did totaly forgot him.
.... because i CAN'T count him as a shortcut because, well, it's not short enough. if you use it, you'll find that you'll have to tap more than twice to do some thing. for exemple, 2g switching need 5 screen tap, wich is TOO much.
with n900, not even this is done automagicaly, with autodisconnect, but it's also be done using a classic app 2g/3g switch, it's done in ONE screen tap ...

doing things is something.
doing things well is another one ....

if it were not, then my ol' windows mobile phone is enough.....
EVERYTHING the e7 is doing, my BA could do that, and in some rare case, BETTER (there is no symbian 3 youtube app, but on windows mobile, it exist ....)
