The World-Wide Media eXchange: WWMX group at Microsoft has released a demo application that lets you create a photo album that interweaves photos, GPS coordinates, and text so that you can view your photos geographically as well as chronologically. Not too useful of an app for today's cameras, but could be a portent of things to come when GPS becomes an inexpensive add-on. Something like this would have been really cool for my Europe backpacking trip.
