Right, I'm not claiming Glass was good, but it at least attempted to use the glasses form factor for something.

The camera to capture 'what you see' seems like using the form factor pretty well.

Mic and speakers, too.

Glass attempted a display, but IMHO, it was unusable, so I understand why you would try the same thing with no display. Or the same thing, but mounted on your wrist (Google Wear).
