Glass makes it so much more convenient to record others. While you can do this with smartphones, the process is so much more obvious with those devices. Most people won't know if they're being recorded or not with Glass. And by putting the device close to your face, it's less likely someone will try to move it aside or block it. It all comes back to privacy being a sense of control over what someone releases to the world about themselves. Glass helps take away that control (as does secret NSA data collection). People are uncomfortable when someone else controls the release or collection of their personal data (images, whereabouts, friends, etc).
