"Matte" or "Anti glare". Is there any of those with already right size to put on top of Otterbox Defender (for the New iPad..)? Any recommendations? I'd like to keep original screen protector in place, if something hits the screen. Optimal solution would be easily re-detachable one, that could be put on in a uncontrollable light situation, but you could leave it off, when possible. Btw, is there any scale used in anywhere to measure how "matte" these films are?
