Share favorite eBooks with your friends, family, or book club. Most eBooks can be lent for up to 14 days at a time. Just choose the book you want to share, then send it to your friend's reader, cell phone, or computer.
Barnes and Noble's new Nook eBook reader looks cool. The part that sets it apart from the Kindle (for now at least), is the ability to lend a book to someone else.
The color touch screen is nice, but the lending is the killer feature.
Your move, Amazon.
