I'm still guessing how Glass would stand up to the performance shown in the demo video. For Glass to work like as shown it would need to have Internet connection everywhere (including ski slops and dessert roads) and batteries need to last for a significant portion of the day. One way it can do is to offload processing + connection to cellular via Bluetooth to phone in your pocket. In which case Glass becomes just interface device for phone like Bluetooth headsets but with camera and tiny projector. The projector could be LED based low powered device with a lens. I think whole thing can be made very cheaply, probably under $199. It would be a very cool thing for sure.

The internet connection is already external. It uses wifi or tether with your android/iphone. So no, it is not going to be cheaper. You can't offload processing because then it totally depends on the phone.
