I've been about 90% happy with this TV. I bought the 60" during BF and the only downside I've found is the flashlighting on certain parts of the screen (primarily the corners) is noticeable during dark scenes. Bright scenes look incredible though. It seems to be hit or miss on how bad the flashlighting is on each panel. It has dissipated a great deal since November, but I still notice it.
Thing that sucks about samsung is that there are no media remotes in the itunes store.
