Summary: Wanted a Smart TV to access internet programming. Had originally purchased a 60" Samsung but found that unit to be to large for the space. Returned the Samsung and purchased the Sony. I've had the unit for over a year so I have some experience with it. Picture and sound are great...as expected. Setup was performed without much trouble.
Summary: The TV came without the mounting screws for the display stand. I had to get in touch with Amazon and had to order the screw from Sony themselves. It was such a hassle. The TV itself is fine, I just wish they included the screws.
Summary: I ordered the Sony EX645 50" in April 2013 after extensive research in stores and online from November 2012 until I purchased it. With all that was out there, the Sony kept popping up as the one I wanted. I was especially impressed with the dark blacks in the store, along with the overall pictures and it had everything else I was looking for. I purchased it on Amazon for a total of $914.48 including shipping.
Summary: I've had this TV for 3 months now and find it OK for the price. Here are a few points which I'd like to mention: 1. Lots of apps: The number of apps supported is pretty good but the interface which is common to a lot of them is very primitive and seems like what is probably easy to program on using whatever Sony offers to the developers. Few popular apps have a better interface to them namely YouTube and Netflix.
