I'll take a Power4,5,6,7,8 or 9 over an ARM IF they manage to produce a low/mid power chip.
Something suitable for a laptop (even if that never sees the light) or a small footprint desktop (miniITX,MacMini that kind of style). Sure a proper desktop would also be nice but not another Power4 server-CPU shoehorned into a 2ton tower (aka PowerMac_G5).
