How can this be, you ask?

Technically, this is speculation not rumor, but The Rollup is including this because 1) so much of itsyPad rumoring is simply assumptions and 2) it's more interesting than most of the rumors.

Apple explains his thinking by pointing out first that each new iOS device has appeared first without a Retina display, which is then added in a later model.

And, he notes, mobile devices are all about trade-offs. "The flagship feature of the iPad (3) is its display," he writes. "The cost, in terms of trade-offs, is that it is thicker and heavier than the iPad 2 because that big gorgeous bright display requires so much more power. When designing anything, you pick one or two primary attributes and you compromise on everything else."
