I've been having trouble finding the perfect sweet spot between HDTV screen size, price, and a 7-foot viewing distance. I found myself thinking "Gee, I sure would have more choices if I could just go with a TV smaller than 42 inches." And then I thought, "Well hey, why can't I?" since i live alone and use the same chair for all my TV viewing, i'm wondering if maybe I could get away with a 36-inch or smaller HDTV, placed on a rolling stand that I could park at close range for viewing and then scoot back out of the way when not in use. What do you think? As long as the image fills most of my range of vision, will I really know the difference one way or the other?
