I'm a big fan of fenders. Obviously, not every bike looks good with fenders but some do. Everyone should have at least one bike set up with fenders. It's quite liberating to have a bike that you can ride in the rain comfortably. As to fenders offering an aerodynamic advantage, I'd love to see proof of this. I can't imagine that it's true and it would take more than anecdotal evidence to change my opinion.
