I researched in-depth for about two months before making this purchase. And, now that I have received it all I can say is, this it is a great buy. I researched specs and made many in-store visits to compare brands, models, features, etc. After the research I had been considering Samsung and the Vizio, coming down to features for price, bang for the buck. I can tell you that for about half the price of a Samsung in the same category I have the latest features; built-in Wi-fi that works like a charm. many widgets available, though there a a few that I was interested in that are not yet available. The major ones are available like Netflix, Pandora, Amazon, Web Video, Vudu, Twitter and Facebook.
As far as picture quality, after spending many hours evaluating many models the Vizio gives the Samsung 6500 series a run for its money and again I state for a lot less money. Super easy setup and it sits elegantly where ever you might place it.
Software updated itself automatically over the built-in Wi-fi connection immediately. Easy to navigate controls, good feature set for controls and more than adequate inputs/outputs. The remote with built-in keyboard, a big plus.
The one area where I suggest you might want to add is the audio. Though the built-in speakers are adeqaute, it doesn't do justice to the set. I used an old PC sound system and it provided great improvement, giving me everything I want. So I suggest you either purchase a separate sound system or the sound bar from Vizio which I have not personally tried. Highly Recommend.
