My 2c.
My friend got it the day it was released and we tested it out on his pc, we loaded CoD4 and 5 both worked, but we had a small sound problem, but we fixed that in dxdaig.
He has since loaded his normal pc stuff on it and has had no complaints of yet.
I glad to see that 7 uses less RAM than vista, I just dont like this series of security questions it asks when you want to share something on a LAN etc.
