I guess that's an open question right now. Even the latest iPad does pretty well with two CPU cores. I also wonder how long it will be before we see phones as large as Apple's defunct Newton platform. How much bigger before people will definitely need purses to carry their phone?
I like you’re ipad comparison. I think you are better off with 2 cores and a graphic card then 4 cores and ghetto graphics. The new ipad has the equivalent of a PC top of the line graphic card to drive the retina display screen. This Samsung phone still has to drive full hd resolution but doesn’t have the graphic power it needs for top games.
I am all in favour of a bigger screen for the new iphone. But Samsung is overlapping the Galaxy note segment with its 4.8 screen phone, it is indeed to big for lots of folks. Since they already have the note going for 4.8” is a mistake in my opinion. I hope the new iphone screen will be between 4.0” and 4.5” and I also hope they will keep a 3.5” phone in the future because one size doesn’t fit all. I am sure Apple could find a way to make an UI that allows “humans” to dial a number with only 1 hand on a 4” + screen size phone.
