I think LockerGnome Apple Lemmings are biased towards Apple, Inc. because they blindly follow the Apple Propaganda & Hype without question. Apple could excrete an expensive bad product, and they would still buy. They media would go WOW! (old technology repackaged). iPhone was Cisco's. WindowsCE, PocketPC, UMPC, TabletPC, Surface were Microsoft.
The same LockerGnome Apple Lemmings will defend Apple Products like pawns in chess.
I use an iPhone, but I'll jump to a better phone & plan after my contract.
I forgot to answer the question: I think the Mac bias is because they want to be like Chris. If Chris worked on a custom built Hackintosh, they'd build a Hackintosh. If Chris gave a raving review of the HTC EVO 4G, they'd get it ... Just a bunch of groupies
