I am hoping Panasonic will follow Sharp and build some huge plasmas in the next few years, I love my S1.
My parents have a Sharp 60" and I quite like it as well, prefer my Plasma but the Sharp is very nice, haven't noticed any off angle issues but I am also off angle to the side and the TV is up high so this could be the difference. I see that Sharp 80" monster in stores and simply start drooling over it. I would only watch from a very slight off angle (with a TV this big) in my room so this could be my next TV.
