Amazon Kindle DX Graphite

July 1, 2010

On July 1, 2010, Amazon released the Kindle DX Graphite (DXG) globally. The DXG has an E Ink display with 50% better contrast ratio due to using E Ink Pearl technology and comes only in a graphite case color. It is speculated the case color change is to improve contrast ratio perception further, as some users found the prior white casing highlighted that the E Ink background is light gray and not white. Like the Kindle DX, it does not have a Wi-Fi connection. The DXG is a mix of third-generation hardware and second-generation software. The CPU has the same speed as Kindle Keyboard's CPU, but the DXG has only half the system memory, 128MB. Due to these differences, the DXG runs the same firmware as Kindle 2. Therefore, DXG cannot display international fonts, like Cyrillic, Chinese, or any other non-Latin font, and PDF support and the web browser are limited to matching the Kindle 2's features.

Amazon withdrew the Kindle DX from sale in October 2012, but in September 2013 made it available again for a few months. Using 3G data is free when accessing the Kindle Store and Wikipedia. Downloading personal documents via 3G data costs about $1 per megabyte. Its battery life is about one week with 3G on and two weeks with 3G off. Text-to-Speech and MP3 playback are supported.
