I like how it also tells you the elevation and compass direction of the shot. Plus it automatically calibrates your camera clock (if you like it to be spot-on). You can set the update frequency to something reasonable like every 15 seconds, so it doesn't drain the battery.
When I do field work I take a lot of photos. I have an extra notebook that I write down where photos were taken. The built in GPS would be quite nice for that...i.e., one less notebook to carry.
