Day of Glass

After watching this video, A Day of Glass, I cannot wait until the future. I now actually want to buy a window just so I can start messing with it just to try to speed up the future. I can almost picture how I would make such a thing, but sadly I don't have the time, money, or knowledge to do it... only the idea. The only problem I have with the idea of glass as technology is that it's glass. Let's face it, we know that glass breaks, and the video shows kids running around with it? I think they'll need glass-shard cleaning machines everywhere. I guess they could reinforce it somehow, but I don't know if I would trust it. Also going back to kids having it, I don't think everyone and every family would own these. Not every family has a computer and these are clearly high-tech computers, making them more expensive and out of the price range for many. Until the law is issued that everyone must have these and they are given out for free, I think it's just an idea.
