I just upgraded to iPhoto '09 and (probably like many people) have decided to try and start geotagging my photos. I have looked into a couple of iPhone apps but they don't work all that well so I did some research and found the Jobo photoGPS (http://www.jobo.com/web/photoGPS.447.0.html). Has anyone used this or anything similar? I've got a Canon 10D which as far as I can tell doesn't interface with any GPS directly (ones that will write the coordinates to the EXIF data when the picture is taken). The main thing I like about the Jobo photoGPS is that it logs coordinates only when you take a picture instead of all the time making it a bit easier to manage. Anyway, any thoughts on this or other GPS units meant for geotagging? Oh, under $200 would be best.
