MAX21100 Sensor for DIMU?

I found max21100.c/h in AQ source tree, and seems that the sensor is only enabled for DIMU v2.1. After looking into its datasheet, it makes me very interested in this sensor. In the first page of datasheet:
High Stability Over Temperature and Time: Bias Stability of 4°/hr

4 degree per hour!!?? This number seems ridicules to me after looking at the price on digikey. Except for reliability in extreme conditions, how can a sensor with tactical grade precision be sold at commercial grade price? Has anyone actually tested this sensor for its stability?

Yes, we have some experimental IMU modules which use this sensor. Don't believe half of what you read on those datasheets. The MAX21100 seems to behave very similarly to the MPU6000 in most respects. The ACC bias might be a little more stable, but it is also has more noise.
