I have no doubt they have a 7" iPad in their labs. Bet they have a 15" iPad in there as well, or something of the sort. R&D does a lot of things, not just developing ONE thing they stick with and never deviate from. People would be amazed how much different stuff is played with and in rough, but never sees a store shelf or even public attention.
This "rumor" is a big DUH.
Yeah, but for arn, when you say these obvious things, after them being rumored for years, and then it turns out that the obvious was true, well that means you must have an inside source!
