Dean Kamen and his mind-controlled prosthetic arm!

You know what, when I read this news in a tech blog, I was just wondering how the amputees will react to this news. Dean Kamen in Carlsburg, California has invented a mind-controlled prosthetic arm, which has come far from the prosthetic arm (like rugged claws) that are worn by the amputees at present. This arm has great sensitivity- moves much like a normal arm, great angular control , sensitive enough to pick a paper, wine glass and to grab a grape without crushing it! This invention is certainly a boon indeed for the people in need of it!
