I do too. I'm in the process of putting in some seating in front of where we normally sit (at about 16') so I can have my face stuck in the screen (figuratively speaking). With the 3d blu ray, I can't see any pixels at the closer distance. The offset allows me to do this with little or no keystone issues.
