I'm aware I'm a little too Windows oriented ;-) but the big advantage of
having an internal asynchronous framework is that input drivers can provide
private hooks so that the input thread can *block* and not poll (that's
precisely the case with DirectInput).

That's clearly the right question, and not only for the input model. Allegro
4.0 may be bloated, but it assumes responsability for many things in the
background and is very easy to use thanks to that.
