I'm a no switcher.

At Large Giant Corp ($LGC), we're XP. Given how difficult it is for a boat as big as this to change course, Vista is probably not happening there anytime soon.

At home, I'ts been W2K SP4 for well over 3 years. And until someone comes up with a patch that fully and thoroughly disables the "phone home" "feature" of XP and (even more so) Vista, that's where the home machines are staying...until I get around to upgrading to (K)Ubuntu or something like that....
