Did you buy a Mac specifically to have PPC inside? Not just for the OS and the company that made the machine?
Keep in mind that if they're going to make an OS that runs on standard Intel hardware that already runs Windows, you'll be able to run it on AMD as well.
If you can't do that and it only runs on Apple made Intel Mac systems, then you're just where you were before, running MacOS on an Apple made piece of hardware. Who cares what kind of processor it has as long as it performs well. If you buy the top fo the line, you expect to get something competitive and benchmarks have shown that Intel CPUs are just as competitive as the G5s. The only places where Intel lost in Apple's benchmarks were places where they didn't turn on any optimizations and compiled for plain x86 that'd run on a 486 machine.
Point being, if it's still "an Apple Mac", what is your problem, really? Are you saying you don't like Apple anymore because of the chip they chose? Or do you just want to make a display of zealous bigotry?
