Case in point: When Kodak wanted to bring out a "single use" disposable camera, people within the company's film division vigorously opposed the move because the inexpensive plasticlenses used meant that the quality of the photographs wouldn't be as good as those taken by 35mm cameras.
Aside from that, the plastic"lenses" on the outsides of earcups pick up up fingerprints ultra quick, but they don't standout too much thanks to the black finish-- we'd imagine it might be easier to see on the blue model.
