I too still run XP (64bit) on my mothership and scout PCs. I've seen nothing of 7 (which is loaded on the wife's scout PC) that inspires me to consider abandoning an OS I have literally tweaked into a symbiotic relationship with me, my instruments, my web presence, my depraved sexuality and gardening tips. I use old Mac G4s in my mulch pile from which spout obsolete, though delicious taters. Apple is more of a pomme de terre starter kit for me.
