I love the mock-up, but use the playstation button/logo instead of "home"?
other things too, L3+R3 buttons?

and could u add a button inside of the d-pad and face buttons that turn them into joysticks?

Like, press the red dot i put into the first pic, and it'd change that side into the joystick-ish thing in the second pic

Can we use the actual keyboard on the n900 yet, or is it all just via the screen? And
