The current Apple keyboard (i.e., the aluminum one) doesn't send a  
key down event to the computer on a tap to turn on caps lock. You  
have to press and hold. It does send a key down event on a tap to  
turn off caps lock. That is, it's biassed against turning on caps  
lock, and towards turning it off. I think this is a terrific feature.  
I hope it catches on. Its antecedents are manual and electric  
typewriters where caps lock had precisely the same behavior (albeit  
implemented mechanically).

However, this makes the caps lock key a bad choice to map to a  
modifier on an Apple keyboard. Half the time, the keyboard won't send  
a key down for caps lock and you won't get the modified key. (Yes,  
the hardware itself does this.) Making this the default, besides  
being unintuitive, will seriously annoy anyone using the current  
Apple keyboard.

This doesn't solve the problem being posed. People change the  
modifier to the Windows key because they don't want the xmonad to use  
Alt key combination. (e.g., I use the Windows key for xmonad because  
I use the Alt key for emacs.)
