Rather than get into a debate about what technically has to be in place to enjoy this "benefit," my read on this is that it's a gimmick to force people into another major transition like HD only without the clear benefits.
I've tried not to be a curmudgeon about 3D and have given it a shot at the Sony Store in New York and at the IMAX theater and both were nausea inducing. Not only that, but the time it will take an already un-subtle industry to tastefully incorporate a technique like this may literally be never. Just like some people will never quite get on board with new technologies like e-mail and video games, this one may just leave more people behind than it brings on-board.
Honestly, as a dealer, I've always seen us more as a shelter from the snake oil and gimmickry rather than just another carnival barker. I've had no clients even ask about it nor any of the tire kickers. Everyone still wants an iPod dock and wireless everything, though!
