Apple buys P.A. Semi

Well I have no idea how this one is going to play out.

If you remember, PA Semi are a group of boffins who Apple was within a gnat's (I need to watch my language) width of buying, when they dumped IBM's line of PPC chips.So the question is, why now?

Surely, his Royal Jobsness hasn't fallen out with Intel already? Is the threat of unapproved clones enough to send him hollering back to the PPC?

No, this is probably about the mobile devices, but then again that begs the question; isn't the Intel stuff good enough?
