E-readers such as the Kindle stomp all over netbooks for reading documents, for multiple reasons. First, e-ink isn't backlit; when you read from a netbook or PC you are essentially staring at a lightbulb. Much easier on the eyes. It can also be read easily in straight daylight. Second, because it isn't backlit, once the page refreshes, there is NO battery drain. With the wireless off, the battery on my Kindle lasts for well over a week with several hours' use per day. Having to jack in can be a major inconvenience at times, and with a Kindle or other e-ink reader you don't usually have to worry about it.
