And I can't consider Intel vs. PowerPC to show the advantages or disadvantages of either platform. I'm sure that if Apple chose Intel and Microsoft/IBM chose PowerPC, we would all be using PowerPC computers right now. We might even be using PowerPC phones and tablets instead of ARM.
Apple was compelled to go with Intel for a number of technical reasons. PowerPC was not able to provide the low heat and low power CPUs required to address the challenges Apple was facing from Intel based Windows machines.
