I love my Kindles and when I got the new Voyage as a Christmas gift, I was so excited. I love the features, the back light, the responsiveness of the machine. However, I have 1 issue with the battery life. It doesn't last weeks like I saw it advertised, which is why I only gave 4 stars. I have the lighting automatic, wifi off (plane mode), I shut it down every night, and I read, on average, 1-2 hours each night. So I may not get weeks, but more than 5 days would have been nice.

Great reader
