Recently I've been to a demo of HD vs Ordinary TV. It was in a studio and not over the airwaves and used two identical Sony LCD TVs'. I have to say that, although I have eyes like an ocelot on steroids, I did not notice that much difference when casually looking. If you really studied the HD picture (which is something that no one does when watching a 2 hour documentary) there was a slight difference in that HD was sharper but this made it look totally unreal. The demo only lasted an hour or so but it convinced me that I will not be paying for HD...if it were free I would entertain it but it does look so unreal. You have to remeber that you are viewing images that would be sharper than if you saw them yourself.
