I don't think I posted about this....
I bought myself a Kindle Paperwhite e-reader for my birthday in December! I absolutely LOVE it! It's a touchscreen and is lit by small lights along the bottom. No more separate book light or cover with a light is necessary.
I had a Kindle Keyboard with lighted cover before. This is smaller, but has the same reading area, it's lighter and more compact so it fits nicely in my purse. The built in lighting is easy to adjust for any situation. If you're in the market for an e-reader be sure to check it out!
The picture is in a dark room. It's difficult to see the size difference, but you can see the even lighting.
