I use my ipad for e books. There is a kindle app as well as a nook app so you can read those both. These apps are free. I also use three public libraries with an app called Overdrive. Again, a free app that most of my libraries in NY use. Last but not least, I get an email everyday from "BookBub" which sends me cheap and free books based upon my interests. I have not paid for books yet. Good luck, reading on a tablet is great for vacations- no bag of books to tote!
