It also doesn't look nearly as dorky as Google Glass did. Google Glass had the problem where it was trying to be an all-purpose life-enhancing thing that people would wear all the time, so it was trying to be both invisible and distinctive. This doesn't need to pretend to be something that you can forget you're wearing or something that you can pair with any type of outfit -- it has a strong sense of style, and it's easier to work cameras into a design that is loud than a design that is quiet.
