Just today I was thinking of why Jobs works so well for Apple: could it be that he doesn't let the company become complacent? Every other big company seems to become complacent. There simply is no need to invent radical new products if you are still bringing in money by the truckloads. But I could imagine for Steve Jobs it is not the revenue that makes him happy, it is the optimum product. So if a product could be better, Apple employees will have fires under their asses.
Anyway, I wish him well.
