The entire photo-taking thing is a bit funny - with the price of storage the way it is, there probably isn't much harm in leaving the camera recording by default and have the user turn it off temporarily if they wish. There's no telling how many amazing photos you could take in a single day with technology like that.

I guess the flip side of that coin is the massive surveillance potential if these glasses are controlled by a third party like mobile phones are; they're even worse than mobile phones because they spend most of the day on your head rather than in your pocket.
