Node Explore, the Tough PDA

If you plan to use a PDA-like device outdoors, this is for you. This ruggedized gizmo has a waterproof casing and can sustain shocks that regular PDAs wouldn't. The manufacturer says that it is "location aware", but I did not see the word "GPS" on their site. I don't know how it knows your position. It seems that it has a mapping software, with points of interest an all. Lastly, I dislike that fact that it runs on a proprietary OS, when PalmOS and WinCE have so many existing applications.
