It would seem that the "killer application" would be to combine the magnetometer with an inertial guidance system. The magnetometer could orient the device when the earth's magnetic field is reliably sensed. Motion sensors (accelerometers) and rotation sensors (gyroscopes) would maintain orientation information when the electronic device was moving around an environment which blocked or distorted the magnetic field. Animals have been utilizing redundant orientation systems for millenia.
