"Looking so dorky" is actually fairly low on the list of ways in which Google Glass fails to be a usable product. Dustin Curtis wrote an excellent review in which he discusses these more serious problems:
Oh whoa, I didn't know that the eye had to refocus to watch the screen! I thought it was more like a HUD and assumed that Google had mastered that part of the system (and was probably the major innovation behind Glass).
Are there competing HUD systems out there which can be worn near the eyes and don't require a refocus?
