Summary: Very happy with this tv. The picture is great, deep blacks. Built in support for netflix and hulu is nice. The web browser is awful. I was surprised by how thin the tv is, and how much lighter than my previous 50 inch plasma. I used the tv speakers before hooking up my audio system and was disappointed with them, no matter how high the volume they just didn't deliver enough sound. But most people would not be using the built-in speakers anyway.
Summary: This TV is absolutely beautiful. There are a couple of things you need to be aware of though: The THX modes turn off the pixel orbiter so be aware of this when you use the THX modes to watch regular TV and the digital optical output only outputs stereo. I connected my Panasonic DMP-BDT210 to my TP-P60GT50 with an HDMI cable and connected my TV to my Pioneer Elite THX Ultra2 receiver with an optical cable - no surround sound.
Summary: I have been enjoying this TV for two months. Great picture and THX light helps for bright rooms. The problem is image retention or burn in. I called Panasonic and their is no warranty for this issue. I thought i was careful breaking it in and Panasonic said their is no break in period. Now I do watch CNBC in the morning and I have a stock ticker line image burnt in as well as the HD+ sign.
