Focal length usage

I recently ran my images through a little program that tells you the number of times you've used a particular focal length, aperture, etc. Looking at the results, I can see why I'm so happy with my 24-105 zoom and 60mm macro. I'm pretty much focused on 28-100mm...
The 60mm macro explains the huge number of shots at that focal length, but clearly I don't get out the 17-24 range very much. The really low numbers indicate shots with a compact camera... There is a hump at 17mm, indicating that I'd probably go wider on occasion, if I had it, but not enough to justify an expensive lens.
