All you say was kinda true for the magsafe ones, I recently saw the adapter that comes with a new macbook air: - no little clip anymore - no long cable anymore - not the smallest Watt-for-Watt anymore (the new GaN ones are smaller) - and of course: no magsafe anymore... But I'm sure that three years from now they will have the "courage" to go back to their older superior design.
