I look forward to the social experiment.

Assume these cameras that takes photos every X seconds (probably checking e.g. pulse/blood pressure to increase/decrease X or going into video mode).

Personal violence will be hard to get away with, for instance. People acting bad will end up on Youtube much more (combine that with face recognition). And so on.

Personally, from future hardware I want a better HUD combined with good chording keyboard -- to run Emacs from the beach.
