I'm getting a Kindle 2 in a few days. Why? I love reading but don't have the time to go to the bookstore or library. I've finished a couple of books on my iPhone Kindle app and want the real Kindle since (1) it's getting hard to read on the iPhone screen (2) you can't "buy" the books from the iPhone Kindle app (you have to visit the website, or use the amazon.com iphone app) and (3) there are a ton of free books that I like and because I read a lot, I might actually save money with the Kindle.
