Barnes & Noble Nook eBook Reader
Barnes & Noble has introduced a dual-screen e-book reader that costs as much as the market-leading Amazon Kindle, but adds additional capabilities. The Nook, based on Google's Android operating system, offers a 3.5-inch diagonal color touch screen for navigation and a six-inch electronic paper display based on E Ink technology. In addition, the device has integrated access to AT&T 3G wireless network to buy books from B&N's online store and access to Wi-Fi for in-store browsing at the book-seller's stores. Other features include the ability to lend e-books among Nook users. The devices costs $259, which is the same as the starting price for the Kindle.
