The Kindle Voyage is Amazon's best Kindle yet. It features a 6" 300 PPI front-lit E Ink display. This is Amazon's thinnest Kindle yet at 7.6", and the front-lit display is not 'sunken' like other touch Kindles. It comes in two models: Wi-Fi and 3G (plus Wi-Fi).
At Intel's Develop Forum last week, the company showed a prototype laptop with a secondary outer E Ink panel. The E Ink display seems about 4-inch in size and is black and white as you can see in the image below:
Intel says that the first idea came from laptop stickers - so you can use this display to dynamically change what you show on your laptop case. In addition, Windows laptops have a very low power mode called connected standby - and in such a mode the E Ink display can be used to show notifications, news, etc - as the display is very power efficient.

The Aura H20 will cost $179 when it launches next month in the US, Canada and Europe.
