Hello Beth -- welcome to MobileRead. I own both a Sony and a Kindle and wouldn't willingly part with either one of them. What kind of books do you like to read? Have you discovered the free books available here and from other sites on the Internet?
It's good that MobileRead and the messages posted by our members were helpful in deciding which reader to buy. Now that you've got your reader, you'll find opinions and recommendations on accessories and books as well.
