I meant those as a joke. The point was that I have no idea what more they can stick in the iPhone to make my jaw drop. I was also going to say "a quadcopter attachment so that I don't need to carry it anymore, and I can summon it whenever I need it".

If they reach the point where it becomes a "faster-cpu-nicer-screen" type event, it means that smartphones have become fully commoditized, and it means the rest of the smartphones will catch up shortly, if they haven't already.
