I still really like my Kindle Keyboard, especially compared to my wife's early generation PaperWhite. However, I would love to have a backlight and am considering picking up an Oasis, Paperwhite, or Libra H2O if there is a good Black Friday deal.

I understand that there are size differences, screen differences, build differences, etc. and I have to sort those out. One of the most important things to me is battery life and after prowling through a lot of threads here I just don't have a handle on what kind of battery life to expect from each of these devices.

I understand that battery life is going to be dependent on how much the device is used, how high the backlight is turned up, etc. but I would appreciate any owners giving me an idea of what to expect as far as how often charging would be required if the reader is used for about an hour per day.

Thanks for the input!
