I'm not entirely sold on the "Innovator's dilemma" argument that "they can’t muster the courage to disrupt their existing revenue streams" in case of Apple - they seem to have been doing plenty of self-cannibalising since Jobs' return - Jobs slashed the numerous product lines to just 4 products when he returned; iPod Mini that cannibalised iPod sales, iPod Nano that cannibalised both of the mentioned, iPhone that cannibalised all iPods. They at least seem to be willing to compete with their own products.
