I'm not really up on the whole GPS/mapping thing. For all of my training, It was all done using map and compass, with little or no use of a GPS. Over the last couple of years, I have seen more and more interesting uses for GPS.. I have been thinking of investing in at least USB GPS transponder for my laptop, but I haven't really looked into the Linux based options for it.
