Yeah the lack of backlight is kind of one of the big Features, giving it a considerable edge over something like the iPad for actual comfortable lengthy reading on the screen, not to mention the insane battery life it has.
Doesn't it have a web browser built in also?
Sort of. Amazon are supposedly trying to improve it though.
I was interested in this until someone told me that it doesn't have a backlight.
Well it isn't that sort of screen -- it's kind of what makes it an eReader. The display uses reflected light like a normal printed page, meaning that you can read it in the sunshine, but need a reading light at night.
