Summary: I bought this thing to use a Chromecast with, but was pleasantly surprised by all the Smart TV features. I didn't think I would care, but since I do have Prime, Amazon Instant Video is a nice feature with the VIERA's. Also, I am a huge baseball fan, so having MLB.TV app built in already is very clutch. Now I just need the NHL Center Ice app. I used CNET's recommendations for color settings and it turned out great.
Summary: I wanted to add some details around the Apps and DLNA feature of the ST60 series TVs since most other reviews seem to gloss over them. I have a home NAS (Synology DS211j) which holds all my media (videos, music, photos) and didn't know what to expect in regards to playback ability from the ST60. I'm happy to report that it can handle a good variety of files and formats.
Summary: Wonderful picture, excellent clarity, great black levels and that plasma "pop" in color that is a joy to behold. I have to give props to the Ceva shippers out of Richmond VA. Two men very quickly and quietly set up the TV in my living room, confirmed the display was working and then they were nearly out the door before I could tip them for their excellent, efficient service.
