They're calling it a "black box for people" (you know, like the kind they put on airplanes) but we're a little disappointed. Sure, the CPOD (which was originally designed by NASA for use by astronauts) can do all sorts of useful things like track your heart rate, blood pressure, skin temperature, etc. and either store it or instantly beam it back to a wireless PC or PDA, but where's the equivalent of the cockpit voice recorder? It probably wouldn't be too hard to make one of these keep an audio record everything you say and hear. Not that you'd necessarily want something that could do that, but still.
