Amazon Kindle

      Amazon Kindle is an ebook reader which uses an electronic paper display, reading Amazon’s proprietary Kindle format (AZW format), and connects by downloading content over Amazon Whispernet, which uses the Sprint EVDO network.

      The Kindle does not need access to a computer. Whispernet is accessible through Kindle free of charge. The day that the Kindle was released, the Kindle Store had over 88,000 digital titles available for download. The initial sale of the Kindle sold out in 5.5 hours.
