Wow. So I bought on the day of an Apple upgrade and I didn't get fucked (instead, I enjoyed the enormous discount that buying in greens gives you - and $50 off). Beyond cranking the top level hard drive up by 20 gigs, about the most interesting thing that's happened to the iStack on this side of the Atlantic (I'm back in Britain now) is that we can buy games in the music store. 
They sell a games pack - £35.91 for nine games - Vortex, Tetris, Pac-Man, Cubis 2, Zuma, Texas Hold 'em, Mahjong, Mini Golf and Bejeweled. Each game is £3.99 - which means you can buy just the ones you like. They have video previews for the games too.
That, and we've got some new nano plastic porn to ogle in the Apple Store.
Oh, and the new iTunes has a download manager which doesn't suck too much. There were huge usability problems with the old iTunes.
One of those usability problems was that if you had the podcast information window open, all right click operations wouldn't work (meaning you had to close the window in order to hit sync on the iPod etc.) - that's been fixed.
Basically, beyond the fluff of movies (I mean, come on, be serious - the iPod video is great, but not for movies), they seem to have fixed all of my major problems with iTunes and given it a UI overhaul. I'm not sure whether I like the new UI (it's very Web 2.0 what with mirrored graphics and so on), but it's a good change. It's certainly mostly usable.
