The Kindle is lighter, smaller, and faster than previous models with a weight less than 6 ounces. The E-Ink display is the most advanced yet and reads like actual paper. New features on the Kindle include built-in Wi-Fi, a book selection of more than 800,000 titles retailing for $9.99 or less, and a feature that allows you to borrow Kindle books from your local public library. The price for the new Kindle is $79.

The Kindle Touch has all of the features of the regular Kindle, plus a sleeker design that allows you to store up to 3,000 books, touch-screen access, a text-to-speech feature, and the ability to access audiobooks and MP3s. The price for the Kindle Touch will be $99.

The Kindle Touch 3G comes with free 3G wireless that requires no annual contracts or monthly fees and will allow you to download books anywhere around the world without Wi-Fi, as well as all of the features of the regular Kindle Touch. The price for the Kindle Touch 3G will be $149.

The Kindle Fire is the most advanced model Amazon has yet released.
