There are perhaps three important points to remember.
Apple's switch to Intel was good, and the usual reasons are well-known. More interesting is that the counter-arguments have been proven wrong.
For example I myself used to believe that once a Mac could run Windows well enough, Mac OS would die like OS/2 because users would simply become Windows users over time.
But over the last few years changes in both Mac OS and Windows have made that problem disappear. Microsoft's business model has changed and 100% Windows is no longer as important as it once was. And Apple have created so many good applications for Mac OS that the system can now offer a lot without any third-party support at all. Suddenly the platform itself has become the reason to run it.
The point is that thw switch to Intel was definitely the right thing to do. Faster PowerPC or POWER CPUs might be missed but none of Apple's competitors have them either, which means that Apple will never be behind; and that is more important than the chance of being ahead speed-wise.
The other point is that anything POWER can do is not out of reach for Apple.
While Apple cannot offer Intel and PowerPC machines as equal products for many reasons, what Apple can do is use POWER where appropriate. For example, should Apple gain market share and try to expand into the server realm more, Apple could offer a POWER-based Mac server running Mac OS X Server. They would have the OS, software to support the system, and years of testing already done. None of Apple's competitors can make use of POWER, not even Microsoft. (IBM are competing in a different market.)
