The glasses are the main turn off for this thing.  Perhaps if you can switch it to 3D mode when watching a movie, and leave on 2D for standard TV watching or something.

What do you guys think?  I think it'll be a wow factor at first, but over time, people will weigh the advantage of the 3D effect over putting the glasses on.
3D DV cams might get a bit of popularity I think though (though this will take time).
