People always seem to want to know what a Matte protector does to the screen so below are before and after screens. What I find interesting is the pixels seems off center on the iPad 3 unlike the iPhone 4.
If you want to see what the iPhone 4 was like here they are
I will still take a Matte protector over plain glass. Fewer finger prints, No glare, Smoother gliding. Easier to clean.
