Has anyone compared the picture sharpness of the 60" and 65" ZT60? I'm wondering if 60" is the sweet spot for 1080P? At which point (e.g. 65, 70, 75) do the limitations of 1080P become apparent at normal viewing distances. And I'm not talking about the charts which show our ability to see details at a particular viewing distance...I'm looking for more of a subjective opinion (if that makes any sense). Why is it that Pioneer never went 65" with the Elites? It's also interesting that LG with their New 1080P OLED chose 55 inch as the standard size.
Personally, I've always liked the perceived increase in sharpness of a 50" 1080P set, especially while watching cable. Sorry, if this is a dumb newbie question.
