Sorry, I meant MS Extreme. I was thinking Experience since that's what's on the XP CD.
Anyway, if you still dont know, it is a show that MS is putting on once a quarter across the country. The broadcast live and tell you about all of the new upcoming products. You get free stuff for listening.
I got Windows XP RC1, Map Point, a pen, a notebook, a hat, a shirt, some trial versions, and a bunch of coupons...
