I too am waiting to hear some views on this screen. If you search back a coupla weeks there was a thread that pointed to the American www.avsforum.com where a chap was close to orgasm in his praise of this new plasma.
Anyone seen one yet, maybe even got one? I was very close to deciding on the Panny 6 but I find the blacks TOO black and u seem to lose quite a bit of info. Was thinking maybe this was the plasma for me, but of course I'd love to hear from anyone who's seen it in action?
I watch my 433MXE from about the same distance as you are intending, and I don't notice pixel structure - why would it be more noticeable than on a 480 res screen where the pixels are larger? Hope this helps.
