For those of you concerned with the 24 hour rental period, I found this workaround at http://http://www.macosxhints.com/article.php?story=2008011923434970 "This works at least on the iPod Nano, though I hope it works on the Mac as well. If you start to watch a movie but do not finish it and the 24 hour period is running out, just start the movie playing on the iPod and press Pause. The movie will remain playable until you close the movie -- even past the 24 hour time period. When you finally decide to stop the movie, you will receive a warning from iPod that the time has expired and will be prompted to resume watching or delete the movie. [robg adds: During Expo last week, I wrote about my concerns with the 24-hour limit. Yesterday, my colleague Chris Breen stumbled on this same solution to the problem. Chris notes that you must choose one of the resume or delete options when you go back to the iPod; he force-restarted his iPod just to see what would happen, and found that the movie vanished. For me, the key question is whether the Apple TV will also support this feature or not, as that's what we'll be using to watch our movie rentals. Until the software update is released, however, that question will remain unanswered.]"
