The focus-follows-mouse policy is indeed superior for advanced users, but 
I think it must be admitted that it isn't appropriate for regular users. 
It breaks the "desk" mental model, with which you always act on the 
topmost element, which is the one that is fully visible.  With the 
focus-follows-mouse policy you can act on any element that is partly 
visible, but that means that you can e.g. type on the keyboard without 
seeing any visible effect on the screen.
