Initially, I hated widescreen displays/TVs - they seemed to me far too 'short' (i.e. from bottom to top). Now, it's the other way around, and any 4:3 screen feels far too narrow!
Incidentally, if a 16:9 TV still has bars on top and bottom when showing some films, what aspect ratio are they? I want a TV like that! 😛
My cable TV provider somehow manages to muck up some channels completely; with a 4:3 signal, stretched to 16:9, then cropped back to 4:3, which my TV stretches back to 16:9 again; meaning objects look ridiculously wide and much of the image is missing.
