I understand you guys talk about the brain couldn't catch up with what the eyes see, hence giving you headache. But isn't that the same with 3D movies? When you seeing a 3D movie, you are also not moving, so as every 1st person shooting game. You can watch the movie for 2+ hrs, and you can play a fps for hours (although tired). How is this different than the "VR ware" we talking about?
I remember when we are in college one of my friend tell me that he can never play Quake3 (you can tell my age now) because his brain cannot catch up with the eye. He had headache after playing it. But I know if you can imagine/generate the interpolate images in between the frames, then your brain can "sew" the images together and "believe" the motion and hence not giving you headache.
I am not a fan of 3D also, but I think it will be cool just for the eye seeing a virtual big screen in a pair of glass. For that price I think it's worth a try. At least you don't need to spend thousands for a big screen tv and it can be view in a small room.
