iPad 3 has an A5X processor NOT and A6 !
And the upgrade from A5X on the iPad 3 to the A6X on the iPad 4 it's huge!
It's Tim Cook really bad mistake to have overshadowed the all new worth buying iPad 4 with the outdated hardware iPad Mini (which is just a repackaged iPad 2).
The iPad 4 is the best and fastest tablet on the market right now.
Apple by Tim Cook is at fault for not being able to sell the iPad 4 properly. They screwed it up big time with the whole iPad Mini stuff.
