Oh if you want to spend some time seeing what's going to come out in the theatres, why don't you head on over to The Apple Trailer section. Most of the big name movies are there and it's always nice to see them in the privacy of your own home.
Only drawback is that you'll need Quicktime which, while bundled with iTunes, doesn't mean each and every person has it.
Oh, and if you want a good browser, and you don't want firefox, for some reason, you could always get Opera. I'm using it right now to write this entry (and it's fast).
