Well....

A friend of mine who is in inside sales of hydraulic equipment says his firm is already talking about using these. Instead of flipping through a catalog, or a data base, looking for product specs they could be called up faster and displayed right in front of you.

The best part is that if the person you are talking to has a pair of these your phone could talk to theirs and they could see what you are seeing.

This would really help when your car is in the shop and your get a call saying, "We found something you should look at while this is in the shop."

It is also possible for you to be able to see in the infra-red spectrum. Or the microwave spectrum. That would be the end of radar detectors if you could see the projected radar beams.
