After I ran through $65 of ink, before we actually tried hauling the laptop around in the desert! When I realized that just wasn't too smart, I hit ebay and found a Palm VII set up for about $30. That model no longer has internet access, so the prices are dropping quickly, but for accessing the data on the GPX files, it's perfect.
I personally have no use for a PDA in my normal world, since I am usually in the same room with at least 3 computers, and prefer the old "folded note in the back pocket" for anything really important and the Palm is small enough to fit in my back pocket for geocaching.
