Apple only became the profitable monster it is today after coming back from the brink of extinction and dominating mobile / music. That's the source of it's "making lots of money."
However, once it loses mobile, as it is surely poised to do, it will no longer be making lots of money... at least, not by current standards. Unless they figure out how to resurrect Jobs so he can resurrect the company again.
Companies like Apple and Blackberry need to learn that no matter how dominantly they control a market, they are only a few quarterly cycles away from completely losing their market position.
