I actually bought mine for work first, then discovered geocaching after a friend told me about it. I work in Real Estate in a rural area. I use the GPS to find people's lots when they are interested in selling. Surprisingly, many people don't know where the land they own is located out here. There are places out here that have no street signs, and no markings. So with a combination of a real estate program for aerials, google earth and GPS, I can find the lots. Not quite as fun as geocaching, but a fun way to spend part of your work day.
