PPC seems dead in that there are no inexpensive machines with a descent bus speed that use PPC CPU's. Besides so many of my PPC games don't work in MorphOS anyhow, thus defeating one of the main purposes of my purchase. So I've little faith in the future of PPC in that respect also, though who knows, maybe these compatibility issues will some day be resolved.
The 680x0 line is great, I'd love to see the Natami succeed since running MorphOS and AROS are great and all, but not quite the same thing as a native environment.
As for AMD. Sure why not! Now a days it doesn't seem to matter what CPU you got, as they all seem very well rounded now a days. It's fast, it's cheap, go for it!
BOttom line, I want it all!!!
