One thing I think is interesting from purely a perspective of watching the the competition between iOS and Android and their respective strategies. In my mind the elephant in the room (or the emperor's lack of clothes) is the screen size of the iPhone. Clearly there is demand for and utility in larger screens. Yet Apple has argued that the smaller screen is a feature not a bug. They changed the size in a way that didn't obsolete existing apps (which was sensible). But they have also made a big deal about the hi res retina screens. I've wondered if the simplest way for them to up the size of the screen is to go with lower resolution, keeping the same number of larger pixels. This could maintain backwards compatibility on apps. Since the resolution is already so high, it seems to me this would be a fine solution (would love to hear some engineers perspective on this). But this would force them to back track on two claims of technical superiority: smaller screen and higher resolution. After using devices with larger screens, the iPhone screen feels tiny, harder to read on, and harder to do things on the web with. (I agree that it's fine for making calls and texting.) It feels like a situation that could turn quickly against the iPhone and all of a sudden nobody wants a phone phone whose form factor was determined by the state of the art five years ago. Again, I'm just observing it as a fascinating case of strategy and tactics among two giants engaged in fierce competition.
