747 wing - this aircraft is amazing at aerodynamic breaking.
Boeing won't agree with you. Boeing will tell you that there is no advantage, (and possibly a disadvantage i.e. increased landing roll), to attempting to hold the nose off for aerodynamic braking effect. The B747 wing is a high speed wing and a shorter landing roll can be achieved by flying the nose gear straight onto the runway as soon as the main gear has touched and getting as much weight as possible on the wheels as soon as possible.
Delta wing aircraft? Well that is a different story.
