I've read elsewhere that audio without the display on is somewhere along the lines of 140 hours. Video playback is very impressive based on the fact that it uses an IPS display which uses much more power than the TNs in every laptop and cell phone in existence since they have double the transistors. I will not be surprised to see a massive fucking battery taking up most of the space behind the display once the teardown photos come out this weekend.
Post more reviews as you get them. If I buy one (and its still an "if") it won't be until the 3G model comes out, but I am looking forward to getting my hands on one next week.

I was impressed with the iPad’s battery life, which I found to be even longer than Apple’s ten-hour claim, and far longer than on my laptops or smart phones. For my battery test, I played movies, TV shows and other videos back-to-back until the iPad died. This stressed the device’s most power-hogging feature, its screen. The iPad lasted 11 hours and 28 minutes, about 15% more than Apple claimed. I was able to watch four feature-length movies, four TV episodes and a video of a 90-minute corporate presentation, before the battery died midway through an episode of “The Closer.”
Oh, and all the while during this battery marathon, I kept the Wi-Fi network running and the email downloading constantly in the background. Your mileage may vary, but with Wi-Fi off and the screen turned down from the fairly bright level I used, you might even do better. Music plays far longer with the screen off. On the other hand, playing games constantly might yield worse battery life.
Apple says video playback, Web use and book reading all take about the same amount of juice. When I was doing the latter two tasks for an hour or two at a time, the battery ran down so slowly for me that I stopped thinking about it.
