There's not much augmented reality in glass; only the turn-by-turn directions sort of qualify. I think the key thing about glass is that it's hands-free. As handy as smartphones are, it's remarkable how much of a difference not having to take the thing out of your pocket and push a button makes.

(The reason there's not much AR is that AR is very power hungry (you have to leave the camera on).)
