So my fiancee and I bought the 55" last Thursday @ Best Buy with their promotional deal. After a few hours with it setup, we noticed a single dead pixel. Took it back the next day, and after examining it they exchanged it for the only other model they had in store. As we were loading it in the car, the only way to get it to fit was with the television laying down flat, with the screen side facing up, as we had done the previous day. The person supervising said they strongly advise against laying down an LCD and blamed the first dead pixel on the fact that we had taken the previous TV home the same way. I told her that it was how the previous employee told us it would be alright to load it, and that we'd take our chances...but I digress.
It has been wall mounted after I examined it for dead pixels, and we love the picture. I am very happy with my choice for a great looking 2D television and since the 3D part was pretty much an added bonus am looking forward to enjoying 3D content. Purchased Cloudy with a Chance of Meatballs from Amazon right away before I realized that it will be sent through the mail with our online registration. I had also already downloaded the PS3 3D stuff with the code from the first television, so I've got an extra one of those to eBay or something.
If y'all have any questions I'd be happy to try to answer them. I will also try and get some pictures uploaded.
