Now 3D on a screen that size would be pretty cool!
I take it that once you have 3D, you would start to watch more 3D and get more out of your viewing experience. The other issue that personally annoys me is the often higher costs for 3D discs.
I do plan/hope to get a new larger TV soon, which will no doubt be 3D, so maybe once I'm there I'll end up changing my viewpoint.
