Heh... but it sounds like something just crazy enough for Jobs to be thinking about it. However, I think his next abrupt and surprising move will be in four or five years, when he changes chip suppliers again.
I think Jobs made the smart move this time. Apple could never buy chips in enough volume to justify the R&D on chips that mostly went to Apple. They got bit twice on that. Now they're with a supplier who will improve their chips whether or not Apple even exists. Plus Apple can just move to AMD with relatively little effort.
