Summary: Has been great so far. Picture is fine. It takes about 5-10 seconds for the tv to turn on and then about 30 seconds for the apps to begin working. The apps are not lightning fast but acceptable. Have used netflix and amazon prime tv apps and they work fine. The first minute can be non-hd as it buffers (but that is with any type of streaming, Those who watch netflix on your computer know) but then it becomes ultra clear.
Summary: We purchased this TV locally yesterday, and not from Amazon. I cannot recommend this TV because there are multiple problems to the TV. The first problem is the remote was broken straight ouf of the box. I confirmed this by using another remote from another Vizio TV we purchased in December 2013. The Amazon or Netflix key would somehow screw up the TV.
Summary: i bought this tv because of the low price. i had researched it extensively and found this to be $200 lower. very pleased, the picture is razor sharp, the larger display is nice, but most of all i like the link to wifi which makes viewing netflix and youtube very convenient and fast. the physical dimensions of the tv are actually smaller (takes up less space) than my previous tv which was 52". its also about 50 lbs lighter.
Summary: The picture and features excellent, and I love the smart TV. Super easy to get to the network to view Amazon Prime, Pandora, etc. I had it shipped to my house. It was delivered sooner than expected and made the whole purchase/set up experience super easy!!
