That's interesting. I recently bought a (cordless) Mighty Mouse, and I'd never noticed any problems with the right click on mine. Perhaps yours is a bit flaky? It sounds like it's not affecting your usage anyway.

I do agree with maximizing keyboard usage (as I tend to spend most of my time in Vim). I was suffering from "mouse thumb" and recently did an experiment with my office PC. I removed the mouse completely and turned on the MouseKeys accessability option (using the numeric keypad to move the mouse pointer around). After a couple of days, it felt as natural as using a mouse, and my thumb felt a lot better.
