It's just one small step in this direction for technology. A parallel can be made: Remember those ab machines? The torso-track was the first one out there, but you could only go foward and back. Then the competition came out with the Torso-tiger which let you go left and right and every other direction. Like the article said in the last paragraph, I wouldn't put my name on the waiting list at this second. I'd definately wait to see what the competition does in the near future.
