I disassembled my PW2 yesterday. The device itself with battery weighs 142g, the battery alone weighs 32g. The case weighs 63g, that surprised me very much!
The battery is a special shape. It is very flat under 4mm thick. I can't find a cheap battery for this. Also most 600mAh batteries weigh about 17-18g. So the weight saving is not as big as I thought.
The Kindle boots powered from a PSU without third contact.
