I'm going to guess that there's not a lot of golfers on this list but if you're interested in a real-life Linux app then take a look at this - http://www.shortgrass.net/Pages/FOCGPS.html
It's got beautiful graphics - easy to use and is run by Linux - a PC under the hood with Linux on a chip connected to a GPS system. You drive around the golf course and the display shows you where each hole is, relative to your location. Overall the device feels like a tablet PC but requires no user interface at all - GPS tells it where it is and it knows where the holes are - all you have to do is hit the ball...
