The most viable seem to be getting a tablet with a pixel qi display. This way the battery life will be good, it's in a good package and you won't need to rely on your own modding skills. However, the first Adam tablet is out of production. It also got obliterating reviews. The only two devices I find is the Adam II which is only available for shipping in India and the SOL 7" android-g.

The Adam II got good reviews by the Indian users but I haven't seen any western review of it. I would so back a kickstarter campaign for something like this.
