Seriously though, at the risk of sounding like a fanboy, it seems clear that Apple is leading the way here.
Highly-portable touch computing is where things look like they're going, and Apple is not moving off of Intel for the Mac. They noticeably didn't pick Intel's offerings for their iOS line, which is outselling the Mac by quite a bit.
I disagree- Apple could have used Atom for the iPad. They Purchased PA Semi, and seem to be taking an interest in that space. I dont think they bought them without at least entertaining the idea that they may be able to transition this to Mac someday.
