Are we just talking just about x86 and clones or all processors in genera.
I believe that the strong ARM, mips, and for the mostpart all of the
processors that drive CE devices are RISC.  On the other hand I have been
informed that the palm pilot runs on a version of the motorola 68000, of
mac, amiga, atari, and sega fame.  It's the processor that just wont die!
