I bought a GPS today

I bought a GPS today. I figure I got an Ipod and a Sidekick II I better get the trifecta of gadgets so I am totally converged. I bought a Magellan Explorist 100 but I probably should have got a 200 cause that has the map. Ahh well it was only $100. Now I can go Geocaching..Weeeee! Update: I upgraded to a 200 before they shipped!
