It is very interesting to me why certain microphones and cameras are fine, while others are not.
Almost everybody carries one of both in their pockets or in their purse. However, it is a no no to embed a cam in a pair of glasses. Building a mic into a speaker is not okay for this guy, but consumer satisfaction is quite high for these devices. I guess to have mics and cams in your car is fine as well.
If it's about babies or security (door bells) it is also fine.
Augmented stuff on your phone seems a necessary predecessor before Google glass can come out for people like this.
It's some kind of anti-sensor attitude that seems to erode over time. I don't think it's about privacy, it seems to be about control. Where's the button on that thing!?
