I spent the better part of 20 minutes last night talking with a friend who got a Kindle for her birthday. She is like me and has shelves and stacks of books. She wasn't really sure whether or not she would enjoy a Kindle in place of a "real" book. I LOVE mine! The idea that in my purse I can carry hundreds of books at a time is thrilling to me and I love describing all the ways that my Kindle is wonderful. I still love a full bookshelf, don't get me wrong, but to be able to have my current interests at my finger tips wherever I am is just too wonderful not to gush.
I also am a huge fan of Audible books. They are great for riding or mindless housecleaning. My problem now is the same as the one I have with my Kindle...too many incredible books to get them all listened to, but I am trying!
