Maybe one of those uber nerds just went and bought like 20 of them. I don't know why people do that stuff, but recently Kotaku had a story about a guy with 46 computers with 46 different WOW accounts. Who played 23 of them, and had his girlfriend play the other 23. That one made my day.
It was only about 2 days old that story and I don't feel like digging it up for a link
