Anyone have an opinion on this? Several reviews are saying it's "barely usable" outdoors - I started another thread about the Evo outdoors, but I'm specifically asking about the matte vs. clear vs. mirrored screen protectors - since it would eliminate the glare, wouldn't that, in effect, make the screen more viewable outside? I've also seen "privacy" screen protectors.. just wanting opinions on each, and pics if anyone has them!
