I had a matte screen protector since I got mine to avoid having to wipe the fingerprints off but it made the pics and screen a little "grainy" looking so I went naked. If you want to enjoy the richness of the colors and nice displays that these screens have to offer, I say go naked. New phones and tablets come out so often and we always want to upgrade so you probably won't even have it that long to have to try and protect it so much. Get a case and leave the screen naked IMO
