I rent movies on my Apple TV. I just go to the store using the interface on the screen, choose the movie and after about 20 seconds, the movie starts to play. You've got a month once you download the movie to watch it and once you start to play it, you've got 24 hours to watch it and rewind, pause.. whatever..

Very cool.

Honestly, DVDs aren't going to last long with technology like that. I don't need to bother with hard goods that just take up room and collect dust.
