I'm not saying that everyone does the same, but if you want to prove your assertion that most Mac users don't use mice, you'll need something more compelling than the fact that they don't ship with one.
For mouse use on the Mac to be the most used input method, over one third of Mac notebook users would have to permanently use a mouse instead of the built-in trackpad. You can go to any Starbucks, airport, or school to see that that is not the case.

Did you happen to hear the term "selection bias" before?
As I've said, I'm not saying that most Mac users do regularly use a mouse (although every single Mac user I've ever talked to about it at work regularly uses one). But to demonstrate whether it's true or not, laptop sales figures and anecdotal evidence based on people's habits at coffee shops isn't particularly compelling.
Of course, some of those notebook owners will also use a mouse. And I'm speaking as a Mac Mini user with an Apple branded mouse, but I guess your original point probably stands.
I wish I didn't have such a reliance on the mouse, but since transitioning from PC to Mac, one of the few persistent problems has been keyboard shortcut support. I can't tell if I've failed to learn sufficiently, or if it's just lacking, but certain applications - e.g. Finder - just seem to be impossible to navigate without a pointing device.

I find I use these (Alfred now, formerly Quicksilver) to open the right finder window first time, eliminating the need for most uses of the controls on the windows.
(also, once you install one of these you'll never need to open the /Applications directory again.)
I for one, use it everyday to open links in a new tab. Cmd+click doesn't work on every website you know.
(I have no proof for any of this. I have watched all kinds of people use computers for 25 years, in all kinds of settings.)
I've worked a lot with FCP (and other editing suites) and PS, and everyone I see, especially pros, seems to make heavy use of keyboard shortcuts and modifiers, rather than fishing around in menus.
