If you're taking pictures of people, you end up having to take dozens and dozens of the same shot because people's expressions change so much. When you get a chance to filter them - it's too late to take the shot again - even if that's just minutes later. Of course you could delete the rejects - but it hardly seems worth the time. Also, auto bracketing for HDR (3 pictures per shot normally), RAW+JPEG and continuous shot modes all tend to generate a lot to store.
