Since the Pronto is dead I think what's needed is an open source solution and hardware with hard buttons. Really taking one of the android phone design and adding hard buttons and even different profiles (e.g. 9400/9600/9800 size and layout). Also other layouts like conventional remote with small touch screen area and extra hard buttons. Devices should have ir in and out (i believe ir is cheap to add (?) ), bluetooth, and wifi tends to be standard.
