Biggest problem I see is in many places and situations, some one even suspected of poking a camera in peoples faces are likely to lose that camera. Maybe be gain a few bruises in return. I know full well that I would not be even slightly comfortable being in view of some one wearing these things. I mean, I don't like the NSA slurping all my data, why on Earth am I going to accept people wearing these things around me? Yeah, claim its some how different, but that isn't going to cut any ice whatsoever with me. Its a camera stealing my image and associated metadata and putting that information out of my control. I don't want people poking those damn things in my direction.

Of course, from a user sort of a well cool gadget POV, I do think its rather cool and would happily have a go on one my self.

So, while I see the merits, I think there will be a huge social problem, which may well negate mass take up. As another poster said, what may well happen is that they will be used in lots of specific situations, rather than be a general use thing. I know I'd probably like using it for specific things, or as a toy or gadget, but out and about? No, Im too pretty..... ;)
