IBM/Sony Apple's biggest threat?

Adrien Lamothe, writing for ONLamp.com, thinks that Apple has gotten itself into a position where their real competition isn't the likes of Dell but rather Sony and IBM. Is he referring to Sony's VAIO series of machines? Nope, he thinks that the Playstation III which will sport IBM's Cell processor will blow Macs out of the water.

Somehow, I doubt it considering that the Playstation, while computer like, has been designed to be a gaming machine. Want to do all your Internet surfer via your game console? I don't.
