While I can't say I've had much time with the television yet, so far I am very impressed. I'm not an HDTV expert, but in my humble opinion the picture is excellent and it has plenty of inputs, including 4 HDMI ports. For those interested, CNET, which tends to be quite critical, published a very positive review of the 52-inch equivalent.
Perhaps the HDTV's most interesting feature is its 120Hz "de-judder" display mode, which generates intermediary frames in order to smooth out rapidly moving images and reduce the image ghosting sometimes associated with LCD displays. This feature is somewhat controversial, as this new technology has been known to cause headaches/dizziness for some viewers and can make the picture seem "too sharp" or "unrealistically smooth" for others. One person told me not to make 120Hz technology a decision factor when choosing my TV.
At first I couldn't tell the difference with it on. I still don't think it helps for your average viewing experience: you don't need it for Conan O'Brien or Brawl. However, I've found that it really does make the picture smoother in scenes when the camera pans briskly and during scrolling credits. Last night I discovered that 120Hz works really well for animated shows from Family Guy to dated anime of arguable value. Upon discovering this, I started a new game of The Legend of Zelda: The Wind Waker and was not disappointed. In fact, the game's animations were so fluid with 120Hz turned on that I found myself playing for several hours.
Setting the 120Hz processing to "High" is probably overkill, but if your TV boasts this feature, do check it out. For gaming, the technology definitely gets my seal of approval.
