Another interesting Android app using it’s compass function: Zagat’s nru (read “near you”):

It picks your location from the GPS and the direction you’re facing to pinpoint nearby restaurants. Nice eh?
Yeah, you’ll look kinda stupid… but then again, way better than unfolding a huge map and spending half an hour trying to locate yourself while becoming a thief target or something. 😛
