I got mine as a prize from the Winter Contest here at MR and I've had no problems with it to speak of. Once or twice I have had to restart it when it froze (but I think that was me either trying to open files too quickly or too many books) but that is the only thing I've had happen even close to a problem. Of course with a built in front light she won't have to hold a flashlight up to the book to read after lights out. I know when I was a 10 yr old my mom (also a Penny) would have to tell me to "put down the book, turn off the light, and go to sleep."
