How come people still keep picking up on this point, it surprises me, especially from a developer. A larger screen doesn't necessarily mean problems for apps, a change in resolution does. That, coupled with the previous rumors of a bigger screen with the same resolution mean that if this is true, it doesn't make any difference to developers because there will be the same number of pixels in the screen. All it means is that everything will be very slightly bigger.As a developer, this will be pain in the ass!
Retina Displays have exactly the double number of pixels with the same resolution, having a second resolution is a giant step to gain one of the crappiest features of Android. I really doubt Apple would do that.
What if this isn't a bigger screen but a smaller device with the same screen on it? Hmm..
