"Mac OS: The button instructs the app to make the window larger to fit the open document."
As others have pointed out, the zoom button is completely arbitrary, and doesn't simply fit the open document.
--- Examples ---
Terminal: fills the entire screen
Safari: instructs the app to fit the open document. (what happens if you have multiple tabs open? which documents gets fitted?)
iTunes: SHRINKS the entire player to a mini player (how did they determine that a "zoom" button should shrink something is beyond me)
---------
These are all apps that come with the system, so there is really no excuse for such arbitrary behavior. There are numerous other 3rd party apps (firefox, filezilla, etc) that simply fill up the screen.
I call it the Surprise Button because whenever you click it, you have no idea what's going to happen.
