"mines a 5 yr old Panasonic 50" and it's just the right size"
My parents have a 50" jobbie - also Panasonic, IIRC, and it's just right size for their living room (in fact, they probably could go a little bigger if they wanted, before it gets silly).
I have a 32" Hitachi here, which is, again, just the right size - and I don't think bigger would be practical. It doubles up as a monitor - and, TBH, it's not very good at that. None of the computers that are connected to it, whether by VGA or HDMI, give a great picture, but instead a bearable one. As a TV, though, it does very well.
