I'm also dubious of the article that it neglects to mention battery life. The iPad claims up to 10 hours wireless browsing/video/music, which to me is very odd. Web browsing should be taking significantly less battery than video, so what is the true battery life when watching full-screen 720P video like the iPad can allegedly handle with full brightness?
I know with my iPod, with brightness on minimum, it only barely managed to meet the maximum Apple stated. I can only imagine how much of a power hog the iPad's screen is at maximum brightness on a 720p screen. I have money riding that the iPad's battery life, max brightness and 720p video is only going to last ~3 hours, 5 at a major push.
