Is an iPad 2 with retina screen. Now I know what you're going to say - that was the iPad 3! But no, that iPad was thicker, heavier, hotter, had worse battery life, and longer charge times - and the 4 is the same. I'd love to see the next iPad get back to iPad 2 levels in all of those things while keeping the retina display. That to me is the one worth waiting for - hopefully it's possible.
