When I purchased my D60, I knew that I liked taking pictures, and also wanted something that could more easily capture pictures of the kids without shutter lag.  However, I didn’t quite realize how much I would actually enjoy the wider aspects of photography as a hobby.

I haven’t outgrown the camera, but there are definitely some things that feel a little limiting:  ability to take older Nikon lenses; auto-focus points are not as sophisticated on the D60; built-in flash commander mode on the D90 to work with Nikon speedlights.  All relatively minor given where I am with photography, but of course there’s always an excuse to search for more gear…

Keep in mind that the actuation count can be reset such as if a camera is sent to a shop for repair/refurbishing (e.g. replacing the shutter assembly).  Also, shutter counts are a rule of thumb.  I’ve seen 100,000 to 150,000 mentioned depending on the camera, but it’s dependent on the make and model and it’s an average life expectancy, not an absolute.  For more information on how to measure shutter actuations, see Finding Your Camera’s Current Shutter Actuations.
