"tell us what you would do if you had Glass" - uh oh, this is exactly how Google Wave started. They are asking because it is a cool tool and they don't know how people will get real value yet.
I'm not trying to be a fanboy here but as far as I can tell, Android borrowed a lot from iOS until it matured enough. Only after, they started experimenting, added great stuff on it and diverged for better.
"Clearly there are hundreds of uses.." - and that was exactly the introduction for the Google code camp for Wave. Uses and value at Google scale are 2 different things.
I don't buy the comparison. Wave was a software product with a complete different paradigm for communication and had huge switching costs. This is a webcam you can wear on your head. The market for portable video cameras was validated in the 1970s.
