IMAX 3D

>I've heard that some IMAX theaters _did_ use polarized glasses

I think it's a well established fact that some theatres use LCDs and 
others show the same films with polarizers. The decision probably comes 
down to logistics and economics. Besides being expensive, the LCD 
headsets require distribution and collection, then sterilization of some 
sort. All of this is obviously beyond the budget of small-town IMAX 
theatres.
