I pay for all my software, games, books, music, and films. Unless they're free, of course.
I would actually pay for some content (mainly professional reviews) on the web, too, but often I find that the price is either too high or the payment system is too clumsy. I would love it if there was a really easy universal micropayment/donation system (with stress on the donation part) where rewarding a content creator would just be one or two clicks away.
That said, I haven't bought any music or films in a long time - instead I have Lovefilm and Spotify subscriptions. I think that in those areas (and possibly including games) subscription/rental/streaming models are ultimately going to dominate.
