Very small form factor. I2C interface so it doe not consume too many IO pins. The HMC5883 magnetometer is a pretty standard part in the microcontroller/robotic community. Libraries exist for arduino and netduino
math is required to use this magnetometer as a compass. Calculating headings requires some complex higher order math functions that may not exist on all platforms, forcing you to code those calculations at a much more intimate level, especially if your microcontroller does not support floating point math.
Should be very useful for robotics, unmanned aerial vehicles or other implementations requiring the detections of orientation. Alternatively this module could be used in any application that calls for a highly sensitive 3d magnetometer.
