Along with the other comments, I too feel for you, on the loss of the pics. Cameras can be replaced , altho expensive, but pics - they really are a snapshot of your life.
I also take hundreds of pics a day, with a Canon S3 IS, but have learned to take a number of fast, high capacity SD cards. At maximum image settings, I'll get 599 pics on a 2 gig SD card. As the card begins to fill, the transfer rate from camera's memory to the SD slows, so I simply replace the SD card on a daily basis (into the camera), and put away the used card into our LOCKABLE suitcases. Over several years we replaced all of our fabric suitcases with either Triton or Dempsey lockable suitcases. They are tough, and cut resistant, and will not collapse. In the event someone does steal the camera, we'll only lose the one day's worth of photos.
