I want my PADD
The PADD (I forget what the acronym stands for) are those thin, handheld devices that are used as input devices and computers on Star Trek TNG and later (no, not tricorders). With this invention they move a step closer to reality. In fact, they'll probably be a considerably thinner.
Imagining two sheets of thin hinged glass being my computer staggers the mind. All of the 'projected' images on suspended glass screens in Sci-Fi movies/shows can be reality. It will be much easier to carry around a PC with you no matter where you go, or to extend several small pieces networked together to create a wearable computer.
With this technology, that commercial where you see the guy with the 'half-glasses' computer interface shouting "BUY! BUY! SELL! SELL!" while pidgeons scurry away from him becomes possible. I love it. I truly am looking forward to the next 20 years to see where we are. I bet I can get a full body replacement by then and essentially live forever.
Don't know if I'd really want to do that though.
