"Hands up who’s rearranged their living room to move all the chairs closer to the screen after buying an HD set? Anyone?"
Strangely with the screen thinner, we actually moved everything further away to make the living room yield more floor space.
On a point of resolution, I have a pretty bog-standard 42" Philips LCD and I have found that a UK comedy prog played from an AppleTV2 still looks pretty good even a very low res of only 448x262. BBC documentaries taken from DVDs are encoded at only 624x352, this appears to be right on the limit of almost "blocking" in very dark areas but is perfectly acceptable to watch. After a while you forget all about any minor niggles and simply watch the content rather than the medium. The upshot is that you can store absolute bucket loads of movie files from DVDs on only a small 4TB NAS unit. No doubt in 4-5 years time that res will be useless, but the TV is only 18 months old and has a replacement warranty for the next 4 years so it's not going anywhere for a while yet.
