Flying cars we still don't have, yet, but a cell phone that contains all of what you need in a mobile gadget for your health seems to be closer, at least if you live in Japan. NTT DoCoMo has a prototype that can act as a pedometer, store workout info--along the lines of Nike+ but more advanced--and even check your breath and your body fat percentage. Before it goes to market, there are plans to add the ability to track your meals and caloric intake. We appreciate the idea that one small, pocketable device can do many different things and this looks to be on the right track. - Image from Cell Phone Digest.
