My sister, Ellie, got me hooked on the Nook, last summer when we were visiting in WY....Her's had the light up feature, which I liked....but, when it came time to buy, got the basic Nook, which doesn't light up .....that's okay....the price was right.... less than a $100....but the next one I get will have the back light feature....
Anyways, I love it and like that having it as storing books got to be a pain....Ernie reads less than I do, so we can handle his "library", but most of mine is on the Nook...
