Personally I think marketing is to blame but it's not the kind this article mentions. I've been wanting to buy something from Apple to replace my PPC powerbook G4 for a few years now but what I have works and unfortunately Apple's marketing department hasn't come up with anything I would rather have. Sometimes I've been tempted to get a "new" G4 just because with all the wear and tear my laptop's case is getting a little shabby.
