What about personal security? I'm curious how you control what is displayed on the back screen and how you lock it out from prying eyes.This is an interesting innovation, to say the least, but I'd like to see a little more creativity with this. The idea of using it as an e-reader it very attractive to me, as constant reading seems to be what drains most of my power. But I'm sure more can be done that just a dumbed-down version of what you see on your LCD screen, like using the entire screen as a visual message alert, interactions from the back screen to the front screen, etc. (a la PS4 controller).Cool stuff, but the security question I'd really like to see answered.
