My photo viewer on the computer does not show the shutter count in the EXIF "Details". It's whatever Win7Pro defaults to for photo viewing. I used the tool mentioned above and was able to get the count, though. My D50 backup camera has had about 30,000 activations (just over half the expected life) and my D7100 is barely getting started.
Download EXIFTOOL. There is probably a lot more in the metadata that you aren't seeing now.
