Pensive it could only be done with Intel. Funny thing with Arm is that they don't have the power that is needed, yet and if they did, they too would have to worry about Intels problem of the power envelope and heat of which Intel has solved with Haswell!.

Oh, to the author of this article, Intel is much closer to the low powered chips that can run both Android (via Motorola phones) or Microsoft with "Haswell" and "Atoms". How long will it take Arm to make a chip that could be put in a MacAir that could do the same?
