Hi there, Im thinking either to use protection on my keyboard or not. On my powerbook G4 i was using one of the iskin silicon keyboard protector. Yes my keyboard is like new even after 5 years of use. looks clean as underneath as well. This is the downside, Over time it leaves a mark on my lcd screen. And its pretty hard to get rid of ( smudges ). As the Unibody screen glass is easier to clean, do most of you use protection for your keyboard or its over rated? i.e. use it and If keys broke get it replace etc..
