CRT
Maybe i'm old fashioned but I have never understood the fuss about these modern plasma or LCD flat screen TVs.
My current (Flat screen, but big behind) CRT set sits on its stand in the corner of the room, I don't care how thick it is, because i'm only interested in looking at the front of it. Maybe someone will tell me I can stick a plasma or LCD on the wall and save even more space, but hey, my walls are for sticking pictures on.
Maybe when they get really cheap I may splash out on a HD TV, which I have seen in CRT flavour as well.
