For AO, it would be the one at work (IBM ThinkCentre).
At home, I have an old Advent (PC World special

), running a 450MHz Intel Pentium III, and a hand-built PC running a 1.7GHz Intel Celeron (components from Dabs.com).
Oh yes, I also have an ancient Fujitsu laptop running a Pentium I

, and an Apple Mac LC475.
