I think it's probably better for Google to stage it with a higher price at first (for early adopters), get a lot of feedback and spend a couple of years to improve the voice commands and then release it to the mass market. I know for me when using Siri, I am disappointed 80% of the time. Siri fails actually at least 80% of the time when I use it, so I really cannot use it, because it's too annoying to keep trying until Siri gets it right. Much easier to type than to try and talk to Siri. Google glass is going to have significant challenges with the voice commands and early adopters will be willing to go through the pain of asking it several times, but the mass market will quickly get frustrated if the voice commands do not work 90+% of the time.
