I bought the Kindle because I travel a great deal and am tired of carrying many books and magazines with me. Hooray! Bravo! This device is amazing. I downloaded three books and the NY Times every day. Not to mention that I can get my favorite magazines. I love the Kindle. I just wish it had a backlight. But otherwise, it is perfect!!
