Amazon Kindle is an e-book reader. More precisely, it is a software and hardware platform developed by Amazon.com (subsidiaryLab126) for the rendering and displaying of e-books and other digital media.[1] Four hardware devices, known as "Kindle", "Kindle 2", a third generation device simply called the "Kindle", and "Kindle DX" support this platform. However, most reviewers, customers and press companies refer to this latest generation Kindle as the "Kindle 3".[2][3][4][5][6] Kindle software applications exist for Microsoft Windows,iOS, BlackBerry, Mac OS X (10.5 onwards) and Android[7]. Amazon's first hardware device, the Kindle First Generation, was released only in the United States on November 19, 2007. The latest hardware device, the 3rd generation Kindle with 3G support for use in 100 countries and territories, was announced on July 28, 2010.[8]
The Kindle hardware devices use an E Ink brand electronic paper display that features 16 shades of gray. Early Kindles wirelessly downloaded content over Amazon's Whispernet using the Sprint EVDO network in the USA. Newer Kindle 2 devices use AT&T's network and its roaming partners for international wireless access.[9] The Kindle hardware device is used without a computer connection, and Amazon Whispernet is accessible without any monthly fee or wireless subscription.[10] All Kindle models (except the Kindle Wi-Fi) provide free access to the Internet in the U.S. over cellular networks, although fees can be incurred for the delivery of periodicals and other content when roaming internationally beyond the customer's home country. The Kindle does not preserve the print edition page numbers used for creating and verifying sources, references and citations.[11]
Through a technology called "Whispersync", customers can synchronize reading progress, bookmarks and other information across Kindle hardware devices and other mobile devices.[12][13]
