I picked up a Reader Touch a few days ago, so I'm browsing through the plethora of covers available to see if I can find out that jumps out as the right one for me... I came across this.

The Proporta leather cover. Seems to be a sizable price discount out on it as well down to £25. But look at "People who bought this also bought... ". Yep, they also bought a device to mount it to the car windscreen, and a USB charger for the car.
What a wonderful idea! And I imagine it's fully compatible with those laptop/steering wheel mounting devices. So you could browse the web, read these forums, shop for eBooks while reading your books on the mounted Reader, all at the same time as driving!
