Well, maybe I exaggerate in the subject of this post. But an article in TidBITs is an excellent source if you're at all interested in reading books on your iPad. Glenn Fleishman not only goes into detail about iBooks, Kindle, and GoodReader but also offers demo videos. In addition, he talks about his experience reading on the iPad. He loves it: "The iPad beats everything I've ever used hands down, no matter which book or file viewer I tried." The video I've posted is Part 1, covering the iBooks and Kindle apps. Part 2 covers GoodReader.
