I definitely wouldn't buy a 3D TV until they've solved the issue of having to wear the glasses at home.
I don't really mind them for a couple of hours in a cinema though. There's just hasn't been a film presented in 3D in ages that I felt was worth paying the extra for. Apparently there were generally good things said about 'Transformers: Dark of the Moon' and 'Hugo' and their use of 3D.
But I still went to see them in 2D.
