Not a fan, and I hope my favorite establishments ban the wearing of them. I'd prefer not to be recorded or "life casted" by someone wearing Google Glasses while I'm just hanging out with my friends and having some drinks. Also don't want some creepers walking around malls recording/creeping on girls be they my fiancee or my niece. We got creeper shot phone pics all over the internet, $10 we got creeper videos all over the net once these things drop. I don't like the privacy implications of these, and unfortunately I don't even have to have a Goolge Glass myself to experience that. I just have to be in the same room with someone wearing them and that makes me uncomfortable.
I agree with most of your points. Google Glass will open up a pandoras box of privacy concerns and litigations. It should make for an interesting transition in society. Could it be that entire nations will end up banning them while others fully embrace? Might become a societal tipping point? One for the history books, no doubt.
