I have had a matte screen powerbook g4 for the past 5 years. After all these years of use, I have so many permanent signs of smudges and lines that do not come off at all. this is one downside that i dislike about matte screens. I decided to switch to glossy and I am much happier. Scratch free glass, much easier to clean. I don't need to worry about the grease and oils from your fingers that will eventually work their way deep into the matte screen and leave permanent damage.
