Watched the first game, and realized that I could hardly see the far court. For some reason, the 3D cameras at Wimbledon were at the opposite end to the normal cameras, and it seems they can't get them quite so high.
So I had a choice between watching the final in 3D at a poor camera angle with glasses on over my normal glasses, or watching it in 2D at a perfect camera angle without wearing two pairs of glasses. Not a difficult decision, really.
I'm completely unconvinced that 3D will ever be worth it. But it's more-or-less thrown in with high-end tellys nowadays.
