I'm surprised to be one of the few board members who have HDTV. I bought my Mitsubishi 55" (139cm) wide HDTV back in 2002, and have loved it since. It's rear projection, so it's quite big, but at that time, flat screen technology was extremely expensive for me. I think that HDMI wasn't standard back then, but it has component cable, so I use that for both my DVD player and the Comcast (cable). The widescreen DVD movies look great in 480p, so my wife and I rarely go out to the movie theater anymore. We love movies. With the 5.1 surround sound in our living room, I have no regrets. I could watch movies on my pc, but it makes no sense for two people to huddle around the monitor and get tired eyes. I hate Comcast for the uncompetitive cost and big, power hungry set-top box, but I can't get the satellite service. For $5 extra, I get about 10 channels in HD, and I have the component output plugged into the 1080i input on the TV. I watched FIFA worldcup games on ESPN or ABC, and it looked TERRIFIC; so much better than SD! I do try to catch The Jon Stewart show when I remember to--good show even though not in HD. The Fox TV series 24 comes in HD, and that looks great too. Also, there's a Discovery HD channel that is mind-blowing in its beauty. I would pay the $5 even if I only got that single channel.
I watch too much TV also, but even if I'm cutting back, I'll continue to watch something. My goal should be cut down to 10 hours or less per week for TV, and 2-3 movies per week on DVD. Whenever the TV dies or whatever, I'd probably get a flatscreen (with HDMI and 1080p) of some indeterminate technology. Gotta have my movies lookin' good.
