Could the current iPad (being 9x faster with graphics) house a "retina" display as a mid-stream revision? All indications point to Apple on the verge of stepping upward to a 4x resolution screen.
There was a distinct flurry of "news" over the weekend about the fabled, but inevitable, A6. Seems there is an ample amount of public murmuring over the iPad 3 (A6 iPad), and it all seems good. Apple is obviously concentrating very strongly on the tablet; I can't wait to see where it goes.
Rumors/news indicated the A6 will be too hot for iPhone/iPod use, but will be at home in the iPad.
With iCloud and some better graphics and processing, the iPad will, in essence, become a full-fledged personal computer. For most people, $499 for such a device is a worthy value compared to some clunky tech for twice the price.
