Dont get mad just because its on kanye west's blog too.
Looks WOW!

EDIT: btw the buttons accually pop out of the screen.

It would be more practical to just change the view on a touch screen, this technology costs more.

that actually looks really good :]

but is it possible to get buttons popping out of a touch screen?

That looks really cool.

I like the concept, and those buttons, lol. Looks like a simple version of the iPhone, only the screen, well nevermind, it has nothing in common. But I still like it..

not bad! Still, I wanna iPhone 3G

looks ugly imo
