I just bought a Optoma 3D projector. I was in the market for a new HD projector and thought..why not. I do think 3D TV is a bit like watching 3d out of a box vs the real cinematic experience, hence I choose the projector for that purpose.
I have been reading a lot about the technology and the way it's perceived by many. It's certainly a "controversial" technology, with it's equal share of lovers or haters, but with a vast majority of "don't care" middle group. For that sole reason I don't think 3D is going to take over any time soon, but it has found a foothold amongst some movie and game fanatics and it may be growing slowly. It depends on the content, Avatar and How to Train a Dragon were freaking awesome, the rest, not so much. Gaming on the other hand is on the rise, as it doesn't have the limitations movies have in terms of depth, resolution, post-processing and things like that.
I have yet to test out the projector in it's full glory, but I'm certainly willing to share my experiences.
