Might also have needed a higher sample rate. For battery life concerns, I can see them implementing some of the fall detection logic in hardware as well. For example, a high shock or shaking could trigger the fall-detection software to wake. Although, with the 60-second period, they probably wake the main processor often enough anyway that hardware detection might not save much power.
