Pros: The overall picture is great. Cinema picture mode out of the box looks perfect to me.
Cons: The IP control for this TV is lacking. No wake-on-LAN and no apparent discrete input selections.
It has a lot of "smart" features which I don't use mainly because I have most of the popular features plus some on my Blu-ray player. The navigation to get to and operate the apps is okay but nothing exceptional to me. I tried out a couple of the apps just for fun but have not used them since. It also has a good number of picture and color settings to fine tune to your liking. The guy that installed my speakers in the room is also an ISF Level II certified calibrator and he said he loves calibrating these TVs because the end result is so good.
I have watched Blu-ray, DVD, satellite and over-the-air sources and all looked good except one of the DVD sources thus far. The DVD source was not bad but it was not what I was expecting. It looked a little grainy and this could of just been the age of the disk since it was about 15 years old. All the 1080p Blu-ray sources were really clean. All Blu-ray and DVD discs were played through an Oppo BDP-103 with HDMI 1 connected directly to HDMI 3 on the TV. With the 1080p sources all I could say was WOW! The satellite source looked really good for the most part. Even though a channel may be designated as HD some of the content was not originally HD and up converted but still looked acceptable to me.
I also tend to watch a lot of news and financial channels where you have banners and tickers across the bottom of the screen. I have never noticed any image retention although I'm not really trying to find any. Several owners have reported image retention and most say it disappears after switching sources for a while. If it is not obvious to me under normal viewing then I think this is not an issue for me. I have another Panasonic plasma that is 6 years old and you will notice some minor image retention when the TV is turned off but it disappears later. I have not noticed this behavior on the ST60 at all so far.
I mentioned the IP control as a con because I use an iOS device for my remote control and I had to use IR to get the level of control I wanted. If the IP control would have been more complete I could have eliminated running a blaster up to the TV and had a cleaner setup. I think this is not the case with the VT60 and ZT60 models but for the difference in cost I can live with IR control.
I have not watched any 3D sources yet but did try out the 2D-to-3D conversion watching a movie on a satellite channel. It appears to work but I am not a big 3D fan to begin with. As another reviewer mentioned the 3D glasses are light weight and pretty much fit over prescription glasses but I am not saying it was comfortable. This is one reason I am not a big 3D fan.
The general appearance of the TV is very sleek with a thin stainless steel rim around the edge of the panel and the panel itself is thin especially for a plasma. The base on the ST60 is glossy black plastic which looks good and pretty much vanishes in a dark room. Be very careful cleaning the base as it will scratch easily. I wiped of some dust with a soft towel using very light pressure and got some minor scratches that can be seen if the light hits it just right. From now on I use a very fine micro fiber cloth designed for cleaning the display glass.
In summary I think this is an excellent TV especially for the price but would have rather had better IP control in lieu of all the smart features.
