That's right for HDTV, if you watch it "seriously" there's plenty who have HDTV and still use it as a noise with flicker in the corner!
The viewing distances come down from Cinema screen sizes of old.

Or you could do what do, have no TV in the room at all! I have a projector so no big ugly TV dominating the room, when it's turned off that is, no screen just a painted wall. It was my girlfriend's (at the time) suggestion and it works really well for me, I only watch specific shows (that MythTV has found and recorded for me) it's not such a good idea if you are the type(s) to leave the TV on randomly. Great for photo "slide" shows too, some photographer friends coming over tonight to see their latest shots on the big screen.
You will find that the Myth themes are all a big huge though :-)
Best thing is it's themeable and you don't have to be a programmer to fix it, so looks like I'll be working on a theme for really big screens and Ian working on one for really small ones.
