i found this: http://www.amazon.com/Sony-GPSCS1KA-Digital-Still-Cameras/dp/B000ME1GUW and for $100 thought it would be really cool to have my photos mapped out on Google Maps/Earth. I travel quite a bit, so thought it would be really neat to look at a map years down the road and see where i've been. anyone have any recommendations for a unit like this? Anyone used this unit? anyone do anything like this?
