Finger Touching, a device developed by Samsung, turns your fingers into the buttons on a cellphone, so you can text faster -- or at least on bigger buttons. It's "easier and lighter in mobile circumstances corresponding to the 3.5G, 4G communication standard." Basically it projects the letters onto the three segments of each finger, and you push what you want. I think this is a pretty clever idea, but I don't need one. Because I don't have a cell phone. Or a land line. I have two rusty soup cans and a very long string. Which is ultra high technology. Don't believe me? You wouldn't know high technology if it called your treefort and gave you tetanus. Which is what it did to me, so I know.
