There is absolutely nothing I despise more than upgrade treadmills. (Yes, an unusual attitude for somebody who makes his living writing software.)
I will say that Monday evening, while my dad was watching Monday Night Football in the living room, I turned on a DVR recording I hadn't gotten to of my favorite team sport, in the kitchen, while putting dinner together (Curling*, the Women's Bronze Medal Game from the Beijing Winter Olympics), and in the intro, they had a flyover shot of the ice, and you could actually see the pebbled surface. That was impressive. But after dinner, I saw the rest of the game on my old CRT TV, and it wasn't any less enjoyable. (Sweden beat Switzerland.)
Given that (1) I do most of my recorded-television watching on screens that are either small or low-resolution, and (2) the only BluRay machine in the house is an early model that takes several minutes to mount a volume, I'm sticking with DVDs, for the most part. I have a couple of movies on BluRay, but that's all, so far.
Luddites of the world unite! You have nothing to lose but your upgrade treadmills!

*Curling may (on paper) look like a bizarre combination of shuffleboard, lawn bowling, and janitorial work, but if you actually watch it, you realize that it's almost like chess played on pebbled ice. Right down to being timed almost like a chess game.
