I think this device will flounder, early adopters will struggle to make full use of it because of all the compromises. Take it on the plane? Why? It will run out of power in 1-2 hrs (if you remembered the full charge before you board). Lugging all that bulk just for a movie on the plane while you look like a black mirror drone.
Then there is TV, it's great if you live by yourself, but what couple has $7k to drop so they can watch TV together. For ~2hrs.
Office work? No thanks, I can't wear that all day and actually be productive.
It's an amazing accomplishment, but who is it for? The ~200k wealthy people who mostly live by themselves isn't going to fulfill an AR revolution for Apple.
I wonder what Jobs would have done.
