code for an A9 that would be acceptable enough for the macbook air. If they were able to make a smaller thunderbolt chip (hopefully to come). and apple does their magical engineering procedures, a macbook air with a much more powerful ARM chip (not just the one iOS devices use) and a good GPU pair (or just let the ARM chip have the built in GPU) that would be a very powerful computer that I wouldn't mind ditching intel for.
Than again, Ivy Bridge or Trinity, would make very beautiful additions to the product line as well.
