Clever idea, Android phone with e-ink screen on the back. But is the battery savings worth the hassle?
It would be much more powerful with some automation that does the right thing whenever you turn over the phone. E.g. if the Kindle app is active, it goes into old-style Kindle mode. If mail is active, it shows the current email. If the home screen is active, it goes into notification mode (shows new email, sms, etc). Having to push content to the backside is fine for a prototype, but likely cumbersome in real use.
It’s really critical that the phone knows which side is facing the user. You really want it to disable the touch on the opposite side.

It kind of neat but until there is a touch enabled E Ink (or equivalent) with pretty fast refresh, I don’t see this taking off. Switching back and forth between sides just looks like a pain in the ass.
