I don't really see Disney as the shining example of successfully replacing a creative genius. Merchandising and re-releasing library content is just standard business school thinking. In fact, the only way Disney has stayed on top of the creative heap is by buying Pixar from, oh yea, Steve Jobs. Unless Apple can do a better job of replacing Steve (and design by committee is NOT the answer) Apple could be in big trouble after his departure.
Anniversary edition iPod classic anyone?
