I agree with what a few of the people said here.
1. Yeah it looks amazing, but what is the power source for all of this going to be? Will these devices require battery power or a charger? How much more costly would a home of electronic glass be on a person's utility bill and if it is costly, I agree: amazing technology, available to the small percentage of the population that can afford to keep it powered.
2. Indeed as amazing as it is, there's a scary element to it that I can't quite put my finger on. Maybe it's all of the recognition, or the fact the various data transfer they simulate seems so easy, or maybe it's all the things around you that you can touch, leaving both input and fingerprint data. When she walked into the clothing store it reminded me of a movie where someone walks into a clothing store and the hologram displays altered to suit that person's likes - that sort of thing is creepy in my opinion; a stranger, a digital stranger at that, that knows my interests? No thanks...
3. Yes! Invest in glass cleaner stock now! "A day of glass...completely smudged by countless fingerprints." lol
