My wife and I just got done watching an episode of the Jamie Oliver Food Revolution show on the iPad. I made a note of my battery life before we started watching it: 88%. When we were done watching: 82%. Now, yes, my brightness is set to almost the lowest setting, which is more than bright enough for a darker bedroom, but even then, that is just plain astonishing. Streaming HDTV over wifi for 45+ minutes and draining only 6%? AND the iPad isn't even warm! Wow. Just wow.
