Yeah, XP works fine, plus I've made so many little tweaks over the years, it's real comfy. Since I'm not even eligible to take
the test, I'd rather just be using it, than playing with it. Mostly because it's more work than play, for me.
A friends Dell PC got virus constipated, and it took me weeks to straighten it out. Of course I only could work on it one day a week, and it was a steep learning curve, but it was fucking work, not fun.
