That's cool. I just got Entourage season 2 on DVD and they actually work the Apple store into two different episodes not to mention that everyone has them, and they have used iChat A/V on the show. I wonder if that is converting any fans of the show, because on IMDB there was a thread about what people have seen on the show that they went out and bought. Seems like that would be one of the most notable things to buy.
I actually use OSX a lot, but primarily because it is a slick UNIX friendly front-end to big Linux servers.
