I am starting to look for a new tv. I currently have a 9year old HDTV tube monitor. So now I am overloaded with terms and options. I am looking for a 42"-50" flat panel. My questions - Lcd or Plasma? 720 or 1080? Now is ee some are measured diag and some are widescreen. HELP! I will be putting the tv in a room that is 16'x16'. Will be viewing from a distance of approx 8-10'. THANKS for any help!
