So far only one person wearing GLass was turned away. Seems like one person, so far bought a pair or these GLass-holes don't go to movies, too cheap for movies? I mean the glasses were 1000 Euros, c'mon!
Camcorders - of course...But perhaps you're forgetting your smartphone (like all other smartphones) has a built in camera and yet you don't see Theatres banning those. So its understandable for a heads-up concerning new technology such as Google glasses.
This is a little ridiculous. Smartphones are allowed in theatres. In fact, for at least the past year they've had a pre-movie game (Timeplay) that comes on the screen before the previews that you need to play on your phone. Then there are reminders to turn off your phone before the movie starts. What is the point of banning Glass? I doubt people that watch low quality screeners would ever have paid to see the movie if the screener wasn't available.
