I can imagine using them within the office, because anything that makes me more productive is totally acceptable "socially". Outside of the office however I have serious doubts to if I'd wear these around daily. My colleague will know why I'm essentially talking to myself to use Google Glass, where as people in public will think I'm batshit (much like people talking on bluetooth headsets).
Once I become very comfortable with them inside the office it's much more likely I'll start forgetting I should even remove them when I leave to go get lunch, coffee, etc.
Plus I'm much more interested in enhanced productivity than I am checking the weather.
What I will give them is the "record" feature could be incredibly useful within the office from day one. I can't count the number of meetings or brainstorming sessions I wish I had on video.
