I like a book, but I absolutely love my Kindle. It's convenient, and e-books tend to be much cheaper than the actual paperback/hardback versions. I like taking my kindle everywhere I go. Where as with a paperback, I wouldn't - extra weight and also because I wouldn't want it to get all crumpled and ruined in my bag.

Also, once I've read something, I don't usually re-read it. So once I finish with an actual book, it just sits on a shelf gathering dust until I donate it to charity or give it to a friend.
