ZDNet – “One of the unique features of the nook compared to any other ebook reader is the capability to loan books to friends, almost like you can with a real book. There are limitations put on from the publishers, but the process is fairly straight forward. The LendMe capability is in beta and support for more titles is still being rolled out in the Barnes & Noble library.”
This is one of the reasons why I don’t want a Kindle. I love lending books to friends. Another reason is that I can’t buy used books on a Kindle.
