ok...
I feel like tapping people on the shoulder and saying "what are u doing, i can't see, u have a better quality camera phone right there"
I do, I have. Last year (not a few week ago), we were at Universal, the Grinchmas show, this guy whips out his full sized iPad, fires up video recording and holds it over his head. I heard some people sigh, but as usually, nobody will intervene, but I will
He actually said, "sorry about that", when we were leaving.
