Amazon Kindle 2 is thinner and in most respects much improved over the first version of the device. Ergonomics are so improved that you just look at the device and want to use it. The price tag of $359 might be a bit too high for some people, but the improved size, improved screen, and improved content selection makes the Kindle 2 much like the iPod nano or the first generation iPhone. It’s very much a game changer in the world of digital books.
