It’ll never happen, but it’s a wild idea that I really like, as a consumer: Give away your OS. When you buy your next Mac, you get all the upgrades to the OS for free, for life. (This assumes, of course, that the next iteration of the OS would operate on your machine’s specs.) It would save that every-other-year $129 tax fom Apple. I skipped Leopard. I’ll probably upgrade on Snow Leopard.
