I have had my 60PZ950 for about 2 1/2 weeks and I must say that I am very happy with it. It is in a room that is brightly lit and performs "ok" when the shades are up (which is to be expected). Close the plantation shutters and it goes from ok to great. When it arrived, the outer box was a bit tattered but the set itself was fine. No stuck pixels, no crud behind the glass, no hum like one of my Sammy's, draws less power than my Toshiba 56HMX195 DLP did, and isn't a room heater like my old Vizio P42... It replaced a calibrated Vizio XVT553SV which does have a brighter, detailed, and more vivid display. However, the LG's display image is definitely more life like and the colors are more realistic. I am using the THX settings which are pretty good for a "stock" setting. I have another 100 hours or so before I pass the 250 hour break in it period. It will be interesting to see what a calibration will do for this set.
Let's see What else? The Vizio Apps section blows the LG Apps out of the water and I hope this is something LG is planning to address. Netflix, YouTube, and Plex all work fine. But the Vizio had at least 3x the amount of apps. Also, the Vizio apps were mostly useful (unlike the mostly useless apps that LG has). The Vizio apps were also much more polished than the LG's apps. I especially miss my TuneIn Radio app and the Facebook app on the LG is H-O-R-R-I-B-L-E! The wand remote is pretty cool, but I like the slide out keyboard on the Vizio's BT remote as it made entering information much more easy.
I have the LG hooked up to a HTPC. When compared, the Vizio also excelled in this area having the most crisp and detailed image I have yet to encounter on a HDTV. Don't get me wrong, the LG's output is ok and I can read and select files in a windows explorer screen from 12 feet away without having to increase font sizes. I am sure that the additional 5 also makes a difference. Bluray, .mkv file, and DVD displayed on the LG is great and I am satisfied with its performance so far.
I have not encountered any burn in or image retention. All in all, I am a very satisfied customer. Keep updating the app section and I'll be even happier. =)
