I'm surprised to see so many people insisting that the submit button should be on the left. Next time you get a dialog box (or equivalent) on a platform that has user interface guidelines, pay close attention to the button placements. You'll find a preference for right-aligned buttons. Windows: "Right-align commit buttons in a single row across the bottom of the dialog box, but above the footnote area. Do this even if there is a single commit button (such as OK)." Mac: "Any buttons in the bottom right of a dialog should dismiss the dialog. An action button, which initiates the dialog’s primary action, should be farthest to the right." (Also noteworthy: "Separate destructive buttons from nondestructive buttons.")
