Anyone else notice that the iPad Mini w/retina display has a density of 326 ppi...same as iPhone retina screen? (Apple also is using same screen tech from iPhone 3GS for non-retina iPad mini...same pixel density). With rumors of higher screen density for next year's iPad, I'm thinking they will change the 10" iPads to 326 ppi also? Would that be too difficult/cause too much "fragmentation"? I mean, the iPad mini doesn't create fragmentation in that the actual full resolution of the screens match other iPads, but, because the screen is smaller, the pixel density is tighter. So, for Apple to improve the display, wouldn't this be the move they'd make?
