I also have CapsLock mapped to Backspace, and use the Dvorak keyboard layout. All of these combined minimize strain on my pinkies and the rest of my fingers, reduces the need for hand contortions, and lets stronger fingers do more work.

Also, on most full-size keyboards, I swap around the modifiers so that I can press the Control and Alt keys with the sides of my palms. This works very well. (I put Control on the inside and Alt on the outside, the reverse of the usual PC layout.)
So while I don't consider the standard position of CapsLock to be ideal, in the end it hasn't proven worth the trouble to move it.
This might sound crazy, but this is my favorite feature of macs. The apple key is next to the space bar so I can use my thumb as you say, and it's used for all major key combos. I also use it with aquamacs for my most common emacs functions.
