The "XP days"? People STILL use XP. A lot of people. A lot of people even downgraded from Vista because they thought it sucked. And you think that the Age of XP is over?! I have three computers, one is the one I have Terragen on, one is the one I usually post from, and the third is just sitting there, under my bed. If one of my other computers dies and my laptop is broken, I just use the one under my bed.
Computer 1: desktop, XP, TG0.9, TG2
Computer 2: laptop, XP, IE, FireFox
Computer 3: desktop, 98, found at garage sale for $3, previous owner didn't wipe hard drive, I got a lot of freebies...
