Amazon has introduced new generation of Kindle that have a new electronic-ink screen with 50 percent better contrast than any other e-reader, a new sleek design with a 21 percent smaller body while still keeping the same 6-inch-size reading area, and a 15 percent lighter weight at just 8.7 ounces. The new Kindle also offers 20 percent faster page turns, up to one month of battery life, double the storage to 3,500 books, built-in Wi-Fi, a graphite color option and more – all for only $189, and still with free 3G wireless--no monthly bills or annual contracts. Also, Amazon introduced a new addition to its family of portable reading devices – Kindle Wi-Fi. Readers who don't need the convenience of free 3G wireless can now enjoy the new generation Kindle for the lower price of only $139.

"Kindle is the best-selling product on Amazon for two years running. We lowered the price to $189 and sales growth tripled. Now, we are excited to introduce a new generation Kindle that is smaller, lighter, and faster, with 50 percent better contrast. Readers are going to do a double take when they see Kindle's bright new screen and feel how remarkably light the smaller 8.7 ounce design feels in one hand," said Jeff Bezos, Amazon.com Founder & CEO. "If you don't need the convenience of 3G wireless, we have an incredible new price point - $139 for Kindle Wi-Fi. Kindle Wi-Fi has all the same features, same bookstore, same high-contrast electronic paper display, and it's even a tiny bit lighter at 8.5 ounces. At this price point, many people are going to buy multiple units for the home and family."

The new Kindle 3G and Kindle Wi-Fi are now available for pre-order on Amazon, and will ship to customers in over 140 countries and 30 territories beginning August 27.
