Sounds about right then, if you are getting 2-3 weeks doing 2 hours a day that's giving you over 40 hours of active time.
I was able to read all 3 millennium novels (each are pretty long in print, something like 600 pgs) on one charge, and still had some battery remaining.
I still don't know why they say "read for 2-3 weeks" rather than using some standard such as page turns (other ereaders do this, usually they mention 8k-10k turns I think).
Had I used this thing in college when I used to pound journal articles I would have easily done a good 2-3 with that alone.
Perhaps off topic but,
Does anybody know if there are projects for @home automated scanning, or services to get books digitized? Commercial devices are really costly, and not available to the public.
