My bet is on Google Glass going the way of the Segway... ...that is to say, ridiculed by the general public, but finding a bit of a niche in certain industries. The police, postal carriers, etc. @cstross did a pretty good job of convincing me that some form of augmented reality would be very useful for the police. There is a real-life push right now to get police wearing cameras too, I think this sort of device could…
I think if someone can succeed at putting similar technology in normal looking glasses it will have a much better chance of success, otherwise I agree.
Edit: as long as it has vim bindings. :)
