3. It is harder to use for surreptitious recording, since a stock phone needs to be placed in line of sight, which is not necessarily the optimal position for common personal usage;
What a load of bollocks. For you to record someone with google glasses, first off, you'll be wearing google glasses and looking right at them. Secondly, you then need to say "glasses, record". Probably twice.
If you wanted to surreptitiously record with a mobile, you simply hold it in your hands, entire phone hidden apart from the lens, and angle it towards the subject. No voice command, no facing the subject, no fuck off obvious glasses.
However, and this is the main issue, if you wanted to record really surreptitiously, you would use any one of hundreds of covert cameras, button hole cameras, watch cameras, pen cameras, even cameras in glasses that look like real glasses. All of which are legal, all of which have been readily available for many years without requiring over-the-top-arsehole-driven legislation to save society.
Not being able to perceive nuance in real life situations is the mark of a basement-dwelling nerd. So, take your self-involve, anti-social, Aspergers view of the world elsewhere.
Dear me, try knocking yourself out of your paedo-terrorist daily mail fantasy for a moment and read the drivel you are spouting.
