This video is rather mesmerizing. I viewed a different video displaying this technology several months ago. I'm excited to see that this touch screen technology is still evolving and may someday be available to the general public. Given enough time, the price will eventually depreciate, as is the case with most technological items on the market, and will actually be affordable enough for the common man to purchase.
