I'm thinking about a Kindle for our seven year old. We're a low tech family and I want to keep it as simple as possible. Mostly I want it to be an e-reader with the ability to link to our library account and perhaps some other limited capabilities such as playing music and audio books. I don't want the kids version with the connectivity to videos and games and such. Is the basic version our best bet? I'm just starting to research but I'd love a little perspective. Thanks!
