Great -- in theory. In practice, its almost impossible to use!

I've never had a lot of interest in photography but when the digital
cameras came out I started carrying one. I've got a great collection of
mountain tops, waterfalls, canyons, alpine lakes, and so forth. I can
identify about 20% of the locations. Geotagging would be nice but I'm
too much of a Luddite.
