So I keep getting mixed reviews for how this screen film affects the retina display. I've looked through reviews on the apple site, PS site, and youtube vids. Most of them say the retina display is still crisp and clean and others say it looks grainy and not good. I love the retina display but wouldn't mind having that smooth matte feel of the film since most of the screen protectors I have tried may be clear but not smooth. I feel that any matte film with the anti glare would diminish the retina display by a little but I am just wondering how you guys feel about the PS HD film for those who have it.
