When reading for long periods of time, customers know that weight matters. That's why Amazon worked hard to make Kindle lighter than ever, so you can read comfortably for hours with just one hand. Kindle is lighter than a typical paperback, and thinner than a magazine and has page-turning buttons located on both sides, allowing you to read and turn pages from any position. Whispernet utilizes Amazon's optimized technology plus Wi-Fi networks to enable you to wirelessly search, discover, and download content on the go. Your books and periodicals are delivered over Wi-Fi via Whispernet in less than 60 seconds. Kindle's keyboard makes it easy to search within a book, across your library, in the Kindle store, or even the web.
