Regarding your first paragraph: Are you seriously suggesting that the iPhone, iPod and iPad are anything but ridiculously profitable without Apple taking a 30% cut from Pandora? Apple's reports to its shareholders seem to indicate otherwise. (And if you're not claiming that, bringing up Sun is a red herring.)
Regarding your second paragraph: I agree with you. The Mac is the best personal computing platform, yet it is not a monopoly. But having a monopoly in the mobile app market does give Apple a monopoly.
