Just seen the 42PV500 in the Panny store in Sheffield and I now I can't decide whether its 37 or 42 inch I just know if I get the 37 then I'll wish I'd have got the 42 but there's always the chance the 42 will be too big. I've seen on http://www.plasmatvbuyingguide.com/1-introductiontoplasmatv.html that the guide is up to 10 feet for 37 and 10-14 for 42. I'm putting this in a square attic space with stairs on one side. In my sitting position my head is 10 feet from the screen and my wife's is 8 so it kind of points me in the direction of the 37 but am I going to regret it? Those with 42" screens how far away is your seating position? Thanks.
