I've had Glass for a couple of weeks and the experience has been interesting. I live in a area w/ about 250,000 people and there are probably fewer than five (including myself) who have Glass. I've been wearing them around town to see how people react to them and so far it seems pretty positive. Some people just kind of look at me oddly, but many people recognize what it is and ask me what the experience is like. This is what I tell them:
Sure, it's great to have access to (most) of the Google Now functionality without needing to look down at my phone. Text messages delivered to the HUD is handy, as is responding to them via voice. For the most part though, there isn't a whole lot these do yet, certainly not enough for average consumers to care. That said, the potential for business/industrial use is HUGE.
Most people's first experience with Glass won't be as a consumer item, but rather as something they use for work. Think construction workers, or people who work in hospitals or laboratories. Many people will be exposed to these via applications in the work environment. You, as a consumer, may not be very interested in Glass, but there are many businesses who want/need something like this for their workforce.
