FIT cellphone concept to make cellphone users “fitter”

I don’t know where manufacturers got the idea that gadgets and exercise buffs would go good together, so I’m genuinely surprised every time I see a new “sports trainer phone”, “diet tracking device” or other similar gadget. These things, of course, more often than not die faster than a flame inside a hurricane, of course that shouldn’t stop new concepts from coming out of the woods now, should it? Especially not one that uses back-to-back OLED multi-touch screens, a compact hydrogen battery and dual-core processors.
