This just shows that Apple may not have the resource to pull off 2 major releases (+iPad) as smoothly as they have in the past. But I think metronomic release schedule is a good thing in general. People loves predictable pattern. The market loves predictability. Btw, seeing the iPad adoption around me... I've never seen (normal, non-geek) people reacting so positively toward a computer\mobile-related gadget as iPads in the past. It does so many things right, it ain't funny.
