The Jelbert Geotagger attaches to your camera's flash shoe and knows exactly where you are when you snap a picture. Thanks to its GPS and compass, the Geotagger can note your coordinates, the direction you're facing, and the time and date you took the shot.
After you get back to photo studio, a.k.a. your step-mother's basement, you can merge this data into the photo's EXIF properties so nerds on Flickr can "ooh" and "aah" that you shot some bird right next to a Starbucks they went to last Thursday. Available now for $283.
Update: Sorry, looks like this thing attaches TO a GPS receiver, and isn't one itself. Blech.
