I've had a Kindle now going on a year. I have sooo fallen in love with this device! It's like an ipod for books. I take it with me wherever I go and have had no problems with it. What's really great is if you find an author you like and want more books from him/her, you can just go to the Kindle bookstore from the Kindle itself and download them. It's an amazing device!
I used to read a lot and then just sort of fell out of it. Now with the Kindle, I can't stop reading! You know it's kind of funny, but now I don't care to read paper books any more. It's gotten so convenient just holding the device and using a thumb to flip pages. With a regular paper book I'm finding I have to keep "cracking" the spine of the book with almost every page turn to just keep it open.
Just to be fair there are other e-readers out there, some being cheaper than the Kindle. However Amazon has the best prices for ebooks and the largest selection of ebooks. And no, I am not affiliated with Amazon in any way! I just love my Kindle!
