Sony no baloney.
Sony has a GPS add-on (GPS-CS1) for its digital cameras that records the location and time data every 15 seconds. The time on the device can be matched with the timestamp on the photo, and the exact location of the picture is added to the JPEG file's meta data, which will allow users to search photos by location!
Now how about that!

Here's some more from the Sony press release:
The 12-channel GPS unit is 3-½ inches long, weighs two ounces and is sold with a carabineer to easily attach to a backpack or a belt loop. To arrange pictures geographically, import the logged data from the GPS device, using the supplied USB cable, and then download the digital images to a computer. The supplied GPS Image Tracker software synchronizes the images on your digital camera with the latitude, longitude and time readings from the GPS-CS1 device.
Once synchronized, photos can become virtual push pins on an online map by activating the Picture Motion Browser software bundled with the latest Sony cameras and camcorders released after July.
