I don't see any reason that Apple Intel-based computers have to have any resemblance to Wintel boxes. The fact of the matter is that they can throw away all the shit that's keeping Wintels in 1982 (the terrible BIOS structure comes to mind) and create basically an Apple-architecture machine that happens to have an Intel microprocessor at its core instead of a PowerPC. I mean, it's not like you can run AIX on a Macintosh or MacOS X on a pSeries. Or, closer to home, you can't run RISCOS on an empeg, despite the fact that the empeg has an ARM in it.
