I've never actually seen a Microsoft commercial on TV except just those 30 secs ones. I am gussing these are more of a commercial guide that is on their website?
Perhaps...
But it is still a advertisment campaign right? They ask the NORMAL people who just use their laptop to mail or to check their bank account, to make a Windows 7 party...
Normally, the geeks would do that, right? *remembers the cool Ubuntu launch party's*
