I have an amazon kindle and I prefer e books over hardback, do you?
I have an e-reader like the Amazon Kindle, but I much prefer hardback books. 
Amazon Kindle has a daily deal and offers a couple of e books in each genre free every day
I recently learned that Kindle has nearly 5.9 million e-books available in the USA!
Amazon Kindle has an awesome selection of e-books and very reasonably priced as well
Amazon.com CEO Jeff Bezos made his employees build the worlds best e-reader before Amazon's competitors could. Looks like he was very successful.
I agree I imagine Amazon has made a fortune selling Kindles, I know I have bought a dozen or so as gifts over the years
The Kindle was actually called "Fiona" at first as a codename.
