Well, I guess you gotta do something to distinguish your phones. The "function defines form" factor seems to have gone as far as it can, seeing as how humans have to use they're eyes and fingers. I guess someday we could have a transparent wafer, or flexible as a handkerchief, or a holographic projection; but we will still need a screen big enough to interact with our fingers.
