Just install an anti-glare film from PowerSupportUSA on my first gen. Air. What made me spend $30 on this was, I saw someone with an Air that had the trackpad button imprinted onto the screen. He said he carries around two Mac laptops in one bag and the pressure from the other MacBook forced the screen onto the trackpad of the Air. That got me worried. I also didn't like the finger print marks my girlfriend leaves on the screen. It took some time to install becasue it is hard not to leave dust under the film. I sprayed a bit of water on the screen & film to make it easier to install. I then use my driver's license to squeeze the water out. What do you guys think? The images on the screen look a bit sharper too.
