Mac vs. PC: Appealing to different demographics
By now you've seen the ads with the kid from Dodgeball telling you to "get a mac". He's the laid-back slacker/hipster whose Mac "just sorta works" with digital cameras, mp3 players, etc. Gotta hand it to Apple. They've framed the argument pretty well. I have no idea who the guy playing the PC is, but he's pretty uncool.
So what's Microsoft's retaliation? Who can they get who's cooler than the Mac guy to pitch their new OS, Windows Vista? Wait… is that Tom Skerritt? The obvious choice!! It doesn't get any cooler than the guy who played Viper in Top Gun (20 years ago). Microsoft does it again!
edit: fixed first sentence.
