I agree with you that any publicity, positive or otherwise, has already been achieved simple because of the announcement of this scenario.
It'd probably be funny to see some Windows bluescreens, maybe see Peter smashing his locked-up Windows computer, or watch the son trying to install W7 on his laptop and subsequently throwing it out the window by the end of the show!
Now I guess we'll have to wait and see if maybe we can't get some penguins onto the show instead -- and I bet it'd be Brian the dog, and the daughter, who'd be the Linux users in the Griffin family.
Family Guy is completely hilarious IMO -- it's one of the very few things I would sit through, if we actually got whatever channel it may be on these days.
