The Amazon Kindle Paperwhite is the latest in the line of dedicated eReaders offered my Amazon. These Kindles feature an e-ink screen, meaning like previous models, its very easy to read. The difference between this model and the previous generation models is the built in light on with the screen. It is not like a back lit screen, which puts strain on the eyes, the light is built into the screen itself. Like previous models, the Kindle is offered in both Wifi, and Wifi + 3G models.
