While I am a fan of Family Guy, I am NOT a fan of the Family Guy & Windows7 campaign.
Stewie used Brian's laptop because he doesn't trust Windows7 on his laptop.
Family Guy re-purposed a scene from a previous episode. It's as if the underlying message is "we didn't' want to spend the time promoting this because we know it's crap"
After you upgraded to Windows7, the best thing you can now accomplish is a Twitter message? FYI: My 1990 Skytel pager is capable of this.
All the other stuff about organizing widgets and switching between application easily: Heads up, Mac/OS and many Linux windowing environments have been doing this for YEARS.
