In this day and age of everyone carrying a cell that can catch you doing something stupid at any given point may have just crossed a line. I saw this on the Daily Mail site, a woman in a San Francisco bar was wearing Google glasses and recording everything around her at random and needless to say if you watch the video the other patrons didn't appreciate it. Personally I agree. I think the bar should have ejected her and I can see restrictions on the use of this tech in the non to distant future.
