WMMiniGPS is a Windows Mobile 5/6 software which gets your GPS data in a really simple gui, showing you latitude, longitude, altitude and speed. It can log all to file and it can export your paths to Google Earth's kml and gpx format.

There's a compass, which shows your direction and you can set latitude and longitude of a point and the program will show you the way to reach it with a radar, telling you how many meters / kilometers there are to cover.
