Uh, yeah, I'd say they're falling pretty far behind actually.
Practically every student in my media studies class was lined up to by fully-loaded MacBook Pro's - the semester began in September but they were willing to hang on until October for the "imminent" C2D MBP. October arrived but no laptop C2D, so, around 80 potential Apple customers now have shiny new Dell C2Ds. Dell gave them a great discount, too.
Apple needs to realise that potential switchers aren't willing to eat quite as much sh*t as long-time Apple fans like us.
