A history of wearable devices, Some hits and misses

First it was a roomful. Then it shrunk down to a desk top. And later it moved to our laps, palms and our attire. Now it's over to Apple's Cook and his team of tech evangelists to surprise us with what they have up their 'sleeve'. But the history of wearable computing is also a history of several misses and a few hits. ET traces this history and offers some glimpse of what one can expect in wearable computing
