Didn't Google Glass had the same issue?
It suffered from the additional issue of negative social interaction - some people (luckily none that I've run into) are really opposed to face-phone (Glass) as opposed to in-your-pocket-or-hand-phone. I don't really understand why people think you're invading their privacy just because of an unusual device form factor.
So it's not about the form factor, but the fact that in case of google glass, the camera is pointing on your head!
