So now we are trying to bring the console wars mentality to TV's. Don't worry about what other people tell you. As someone said, decide on your budget, forget the hype, go to the shop and try out a few of the TV's in your price range with different sources, decide which one looks best to your eyes and be happy with that.
People talk about 720p this and 1080p that, viewing distances, 20/20 vision blah blah blah. I can't locate the paper at the moment but there is research to suggest that when subjectively judging TVs in a blind fashion, resolution is only about the 4th most important factor in judging image quality, with colour, contrast and (something else) all having a greater impact on people's perception of image quality.
Don't buy into the hype, a crap TV that can do 1080p is still going to be a crap TV.
