Was in Harrods yesterday and tried the samsung 8000 46" 3d and the Sony (have a Sony at the mo and it's very good).
Both had good 3d but the samsung glasses were much nicer to wear over my normal glasses. The Sony were too heavy.
So I think I might just go for one of these 46" 8000 series samsung led, the 3d was stunning and I want to try 3d gaming with cod, plus I subscribe to sky world so will get the 3d channel free. Annoyingly I just missed the £200 cashback though.
Good choice, when I had a demo on a Sony set, I thought the glasses were heavier too, the samsung ones fit well.
Although the Panasonic ones are probably the nicest ones I've tried.
Oh and COD in 3D is going to be full of win IMO, can't wait.
