ive seen diet and workout scanner businesses before, their biggest obstacle is getting the hardware at a cheap price and making the body scanning process as seamless as possible, tango seems to solve both problems, though, I stopped following its development once I realized I wouldn't have the cash to buy it QQ
first phone with google tango ships next week!
