Any GPS geocacher's here?

It is pretty interesting when you get looking into it, that some cells phones, PDA's, and almost all computers, can be made into GPS recievers by adding an antenna and the software. I mean, you already have the display, just add the maps and antenna, good to go, right?

I want a automobile Nav intergated with a radar detector so I only have to plug in and hang one unit on the windshield.
