Because his isn’t going to be able to go back to his old G4.
I didn’t hear about this until today when this movie was released, but it seems that some guy at HelpMeGetAG5.com said that if he got enough donations for a new G5 PowerMac, he would blow up his old G4. Well, he did get enough money, and he did blow it up, an dhe has the video to prove it. The sites down now probably due to the sheer number of people trying to watch the video, so you can enjoy it here, free of charge. How nice of me.
