I mostly agree. There is one use case I've seen and that's taking fast photos when you can't fumble with a phone. When I'm driving around, I always notice things that I would love to report to the city or code enforcement like a streetlight that is out or a dumped mattress or an abandoned house with grass 2 feet high. I forget by the time I get home and I don't want to pull over to make a note. Google Glass would be perfect to just press a button and take a picture with the coordinates encoded in the image. Maybe also a voice memo attached.
