Cool idea. But I'm not seeing a practical application outside of the "hey this is cool!" factor.
I heard that even early Apple people would say "A computer in every household", and people would ask, "What would I do with a computer?" and their best answer was "It's a great way to store and file your recipes."
But we are starting with something more simple, and not trying to promise everything to everyone. That does mean looking for initial use cases that will take off early.
3d tv flopped, it could have been a start of something, terrible as it was. Lightfield cameras didn’t take off either, maybe because of the price. Let’s hope this could be a beginning!
