This, plus mature augmented reality, minus device's screen... that could start to get very interesting. Maybe something like a wearable (iWatch or some such) with this, plus an AR interface creating a 'virtual screen' to interact with. For my full sized device though, buttons have serious advantages that don't go away until the motion sensing is hooked up to a REALLY smart computer.
