When I say 'all screen', I'm talking about the equivalent of the side bezels on the top (where the ear-piece is) and bottom of the device. Sure, technically it's not amazing, but from a design perspective it will have a very large impact of the general aesthetic of future devices -- especially if designers are determined to minimize bezel sizes.

Of course, with an all touch device, this calls for a modification of the UI to accommodate such a model, something that honeycomb currently employs.

Again, it's not revolutionary, but it's interesting that there is still room for design on a rectangular touch-screen device. I'm sure if/when we see such devices, they will look incredibly sexy.
