And ironically we now use 'box-sizing' to recreate that very box model. So basically the default box-sizing value is now largely ignored except in the rare case where it's nice to enable it for an element. Pretty much ends THAT debate!
Not that I'm defending MS; I once made my living by mastering all the arcane spells needed for IE compatibility. Still, it is a kind of vindication in this one case.
