Oh, huh, I was going to kvetch that IBM PPCs don't support AltiVec, outside the G5, and therefore it'd be annoying for running software that supported it, but I looked and they've actually incorporated it into POWER6 on up. Whaddya know.
Yeah, it is too bad they have no interest in the desktop market anymore - do they even still make POWER-based workstations, or did that end when they spun off Lenovo?
