In response to Matt Minnis' review of the DAS20 dual-axis clinometer, what are the advantages over a dual-axis accelerometer like the ADXL202?

The usable static range of the DAS20 is listed as +/- 20 degrees, while an accelerometer in a static tilt environment will be usable in the full 3D range. Additionally, the size of the DAS20 exceedes the surface mount ADXL202 or even the through-hole ADXL202-EB. I couldn't find a price for the DAS20, but the Analog unit is $10 for SMD or $30 for through-hole.

Both sensors are subject to linear-acceleration errors and not be usable for attitude reference without angular rate sensors. Am I missing something?
