What exactly is the material on the glossy display my brand new 13" MBP? I definitely need a good screen protector because I have an iskin keyboard protector and when I close the lid, it smudges the screen. I am afraid that it will trap dust and whatever and scratch the screen when i travel! Any good screen protectors that won't dull or matte the screen? I LOVE the glossyness but I'd rather not have it scratched up. I love the crystal film by power support on my iphone because it keeps the brightness but they dont make it for the MBP unibody 13" unfortunately. I've checked out shaggymac but i dont know how well that works. Also, anybody familiar with trackpad protectors? I have the palmguard from Moshi. Is the trackpad really necessary? Does it wear down over time? Thanks in advance!
