Geocaching Australia

This is kind of cool.

Good idea but let's be honest the display sucks, but I guess that would add to the price.
A better option would be a tablet app.

Cool idea... but kind of redundant? Going to be hard to read on the go compared to a GPS or Phone with a map display.

I have got a Raspberry Pi sitting on my desk, but at the moment it will probably become a small util server for home that will serve up weather data, that is unless they manage to get android running on it before I get around to that project.
