Launch date: 2002
Fatal flaw(s): Clunky design, slow hardware
Never mind the fact that Xybernaut had to enlist the help of Hitachi to actually release its wearable computer, and the fact that it went bankrupt. Lets focus on the fact that when Xybernaut introduced this product at the 2002 Consumer Electronics Show, some people actually thought it was a great idea. Look at the thing! It looks like a broke Halloween costume. Not only that, it ran on Windows CE and cost a cool $1,500. For that money you could have bought a real computer and kept your pride.
