Amazon Kindle DX

May 6, 2009

Amazon launched the Kindle DX on May 6, 2009. At 9.7 inches, this device had the largest Kindle screen until the release of the Scribe. The pixel density of 150 ppi was the lowest of any eink Kindle device. It supports displaying PDF files. It was marketed as more suitable for displaying newspaper and textbook content, includes built-in speakers, and has an accelerometer that enables users to rotate pages between landscape and portrait orientations when the Kindle DX is turned on its side. The device can only connect to Whispernet while in the U.S.
