Just another reason, for my part I put a sticker because the translucent apple used to let the sun shine through to my screen while outside. It actually took me a while to understand that it wasn't a screen defect. I put a layer of aluminium foil (held by double faced adhesive tape) because that's the thinnest completely opaque material I could come up with, and put a sticker on it because it was quite ugly otherwise.
