I think the other reason why people didn't want to adopt Google Glass, is the stories about other people objecting to people wearing them–primarily because of privacy concerns, that the devices were capable of recording video, and that while a phone camera can record video too, it is somewhat more obvious if someone is doing it with a phone camera than with Google Glass. If a product is going to be a social hassle, if other people and businesses are going to object to your use of it, a lot of people will decide the negative social consequences aren't worth it.
Something like Google Glass specifically targeted to people with disabilities would be more acceptable, because someone using it can always say that it is for their disability, at which point most people would be more forgiving, plus if any business tries to ban it they run the legal and PR risk of being accused of disability discrimination.
