IBM shipped a lot of PowerPC machines also. I think they still have some current machines on that architecture.

If I remember right, that was what caused Apple to switch to Intel. IBM just couldn't get the heat and power consumption on the G5 down to a level that would make it feasible for laptops.
And yes, I think that's right about not being able to get the heat down for laptop parts. That's still over a decade after the PowerPC 601 that competed with the Pentium (P54C). By 2006 it was pretty obvious that x86 had 'won'. DEC Alphas were discontinued, Sun was well into financial difficulties, and SGI (MIPS) was in serious financial trouble, and Apple was moving to Intel.
Side note: A lot of these arguments really happened over 20 years ago. This has actually been a really nice walk down memory lane.
