I think it's too inconvenient to become the norm. If I want to watch a movie with my friends, we'd all need the glasses, and sometimes I could have like 8 friends round. I don't want to own 9 pairs of 3D glasses. And even if everyone had their own pair, someone would forget them, and then that's it, we can't watch the movie because it wouldn't be fair on the guy who forgot his glasses. We can't blame him, he's only human. Like other people have said, it's a fad. It'll blow over. I just hope the whole motion sensor thing blows over too. But that's another rant altogether.
