I just thought of something else that would be real nice. Get rid of sd cards. They have the little monitors that you can view the pics in the woods. Give the camera more internal memory and then have something that can transfer those pictures into a portable reader. Then you could go from camera to camera, plug it in and it transfers what is on the camera to the reader, then take it home to view the pics. Thus retrieving all the pics without losing or switching sd cards. Does that make any sense?
