I can't see the logic of Apple moving to a 16:9 elongated screen for the next iPhone. The general consensus on this site seems to be that it's the only way to offer a larger screen without breaking existing apps, the size difference being offset (supposedly) by a black bar at the top/bottom of the screen.
My question is, if this is a solution for a taller display, why can't it be for a wider display as well? Why couldn't there be black bars on the sides of the screen as well as the top and bottom?
Surely the obvious solution is the one used on the iPad when displaying iPhone apps - just have apps displayed in a 3.5" window in the centre of the screen with black/grey/blue bars running around the edges.
This way Apple could increase the screen size to whatever it wanted (4"/4.3"/4.7"), using a standard resolution (720p), while maintaining retina status, without having to worry about compatibility with existing apps.
Can anyone think of any reason why this couldn't work, or why Apple would prefer to go down the 16:9 route? (from a technical standpoint - I'm not really worried about the 'it wouldn't fit in my hand' argument).
Thoughts?
