neon32, you need to update your opinions.
-The Mhz war -is- over, its about multi-core now.
-There are passive x86 CPUs, (try Via mini/nanoITX for a start). I think we'll start to see more in this area in 6-12 months.
I agree it's no good having just one type of CPU out there, but the x86 is fortunate in that is has two major developers who constantly try to out-do one another on price and performance. Keeping innovation and value to the consumer extremely high.
What does PPC architecture offer, apart from some vague "spiritual" heredity to the 680x0 of yore? No really "real" (ie, Built and sold by Commodore) Amiga was built with that CPU. Yet they used x86 based CPUs in several machines...
