So I finally got my Panasonic 60ST60...
...and all I can say is:
Stunning. Absolutely stunning. I was flabbergasted at how good a telly's PQ can be, out-of-the-box - and I haven't tried a blu-ray movie yet. Don't have a 3D movie so haven't tried that yet as well.
Smart features are neat and easy to use, though the Internet is a bit sluggish, though that maybe due to my wi-fi router location. Working on it.
All in all, very happy with the purchase indeed
