The way I look at it is this,
Back say 30 years, the people of that age never would have even imagined to have the kind of technology that we have today (iPods, Smartphones, Hybrid cars, Webcams, etc.) And now today, these items are part of our daily lives. And they aren't all that expensive either (debatable). So I think this video has left us in the same position as the people 30 years ago. We believe that this glass technology is off that charts and not practical and such, but say 15 years from now, these kind of items are going to be part of our daily lives, and many households will contain these sort of appliances (also debatable).
Whatever. I'll take the hate. It's just my opinion.
