One of the regulars where I'm working saw a kid with Google Glass the other day. That's the kind of shit you have to deal with being on the edge of the Brown University campus.
I've never seen anyone wearing these (I'm in rural Wisconsin for fucks sakes). I feel like if i did, I'd probably have the same reaction as seeing someone with a really futuristic looking bluetooth earpiece. Something along the lines of "get a load of this asshole!".
I threw a house party during what was apparently the beta period for these things and some pathetic nerd I didn't invite showed up with these on and stood around the whole time using them in a manner that betrayed his burning desire for somebody please anybody to ask him about them and to my knowledge nobody ever did. He drank a light beer that he had brought himself and left after an hour.
