I for one am a supporter of the glossy (Glass Protected) screen... One of the main reasons being that with the people I work with often they find it necessary to put their grubby little fingers onto my screen when they are trying to point thing out or explain them. On my old MacBook Pro I used to get very nervous - now, its no problem...
You get these screen cleaning kits: Static free Brush (To brush away dust and take the static charge away from the screen) Compressed air can work to but in Hot, Dry Conditions this can charge the screen more. Then a quick spay of the cleaning solution and a gentle wide with the static free cloth and moments later the screen looks as good as new - no finger prints, no streaks and no dust for a couple of days... 🙂
