Next Gen iPod Patent Has "Touch Surface" On Back.
from Gizmodo.

I thought this looked cool: a scroll wheel on one side and a touch screen on the other.

Patent.

i think the entire touch interface is on the back, with the front being a non-touch screen. so, would this kind of work like a trackpad only with force feedback?
