I've said it before, and I say it again. The next big thing is the full OS X on ARM.
I would have doubted this even a year ago, but for MacBook Air and Mac mini, I think it could happen with A8. Wonder if they could manage a 20+ hour battery life MacBook Air Retina w/ A8, 12" screen, reeeaaally thin, maybe 8GB RAM, 256 and 512GB solid state storage options. That would be an exceptionally tempting machine!
