If you can find a GPS with a compass in it you'll have more fun. I don't know about standalone GPS units newer than 2000 (then, the higher end ones had it, the lower end ones did not).
Any real GPS should be accurate enough for geocaching. Cell tower triangulation is not accurate enough. The iPhone 3G has a real GPS reciever while the 2G does not. The newly announced 3GS has a magnetometer (compass). I haven't used the iphone's software so I can't tell you whether it's convenient for asking "how far away and what direction is (37.785945,-122.39454)"
As for your poll: I also maintained a cache for a few years (though someone else took it over a while ago)
