No redesign no bigger screen. I can already see the headlines of tmrws newspaper "Is Apple Already Sinking Under Its New Leader?"
Rolling out "bigger screens" can't be the answer every 1-2 years. After 3-4 years the phones will have grow too large. The iPhone 4 just got a major screen improvement. It is highly dubious that the next model would get a major upgrade in the exact same component. Something
else is far more likely to get a major upgrade, than the screen.
Similarly, after Apple made such a big deal about the pixel density of the iPhone4 screen, it is extremely unlikely they are going to turn around and
reduce the density the next year. (In order to keep number of pixels the same but cover a larger area they spacing between the pixels will have to increase.)
Boring. Who cares for more ram, the iphone 4 will handle the new ios just fine considering the 3gs is even getting it
But the iPhone 1 and the iPhone 3 didn't really get iOS 4. You will care alot when IOS 6 doesn't run (or runs in hobbled mode) on your iPhone 4 because it doesn't have enough RAM. Specs often do matter, because features often need "specs" to run. The particular values ( 1GB , or 1.5GHz) are what Apple is trying to draw attention away from. Largely because people retreat into overly simplistic ( MHz myth) mechanisms for evaluating "A" versus "B". Instead of solving a multidimensional problem they just pick the "bigger" Hz number.
+ unless devs invest in extra apps for the "special" new a5 and ram iphone ... no one will notice any difference
Now. If your objective is to dump your phone every 1-1.5 years to snag the "latest, greatest" then sure there isn't enough time for a large number of developers to pass your phone up. Once at 2-4 years, then have a problem.
However, if everyone is playing the "dump phone every 1-1.5 year" game there is low motivation for Apple to do quantum leaps each year. You're going to dump phone anyway with whatever incremental differences popped up over that short amount of time.
