I've had my HD widescreen for over a year and I still love it. For the most shows it just 480p, but it still is a superior picture to my 33" conventional tv.. When I pop in a movie the picture is upscaled to 1080i. I do this just to see a great picture as I'm bored with most of my dvd's and need to get some new ones.
Haven't experience true HD yet and don't know if I'll hop on the bandwagan. But the novelty of watching HD upscaled still hasn't worn off. Any comments?
