That really sucks that it scratched up your disc.
As for the other people who moved their system while the disc was spinning that is definitely a no-no with the 360. This problem was talked about long long ago (http://www.llamma.com/xbox360/news/Xbox-360-Game-Disc-Scratched.htm ) That is from 2005.
That's why MS started putting those stickers on the dvd drive tray that say something along the lines of "Remove the disc from the dvd tray before moving the system". (note: I'm just translating the Japanese from my sticker as I don't have a sticker in English)

Me since the games were revealed, the fanboys since E3."
