exactly; it's when it is N > 2 (or some other fixed constant we find through 
trial and error) that alignment to the trigger event (e.g. mouse press) 
becomes better.

that's sort of the problem: for different ratios of popup to target, the answer 
of 'what looks best and is easier to use' changes.

for N < 2, sure. for things the width of the taskbar, it really sucks. i tried 
this in the past, which is why it stayed left aligned by default.

i'm not sure it would be magical in the *bad* sense. if the "magical choice" 
is simply more convenient in each case (and the user does not need to adapt 
much or at all when the choice varies) then it won't matter.
