Another use of GPS information in photos would be to auto-label your photos. This would work by querying some web service for a label associated with a given set of coordinates. For instance if I was at the Seattle Center and my camera was facing the Space Needle when I took a picture that photo would get labeled "Space Needle" instead of "DSC0002752".

The Space Needle example is a best case example but even the worse case example of labeling my photo "Seattle WA 1" or just "Washington 1" would be better then the alternative.
