Advantages: Rich blacks, great colours, good motion clarity, slim chassis
Disadvantages: Interface could be smoother, 3D glasses too expensive (£50!)
We've had this TV replace a low-end Sharp LCD TV and I have to say the two are pretty much incomparable; the Sony having really vivid and rich images over the washed 'backlit' images of our previous TV. It's not absolutely perfect though it's pretty close.
Firstly, blacks are really, really inky and saturated provided they're adjusted in consideration of lighting. I've been really impressed by how good blacks are on this panel and they're best I've seen on any of the TVs or monitors in our house by a long-shot. In the extremes you can see some very minor blueish 'clouding' with the backlight on max with dark pictures in dark conditions. Further, blacks do get less saturated off-axis. Both these things aren't anything you'll be able to avoid on any other LED-LCD really, the latter being a side effect of the IPS panel used.
With this said, the deep blacks make for some really nice contrast - pictures can be really colourful - and in general the picture on this TV is very pleasing to watch.
Secondly, motion clarity is good, but not great. The sweet-spot is the 'clear plus' setting; fake 200Hz achieved through motion smoothing and backlight blinking. It's not important you know what this is, just that the latter method massively reduces picture brightness. There's other settings which don't reduce brightness but on the contrary smooth less and seem to bring out the 'soap opera effect' more; meaning some sources, mainly films, look a bit 'sped-up'.
Whilst the TV's motion clarity isn't perfect it's a darn site better than our older Sharp LCD TV.
Outside picture quality, this TV remains pretty strong. The features on this TV are brilliant, the most used being the BBC iPlayer and YouTube apps. They're not perfect and do experience the occasional hiccup but otherwise we've been pretty impressed.
One thing I will say is that Sony should have perhaps put a stronger processor in this TV; menus do exhibit some minor jitter with their fancy side-to-side transitions. Considering it hasn't already been fixed by a software update probably means it can't be improved upon.
Audio quality is good when you consider how thin this TV is - the chassis is one third of the thickness of our previous TV at 4cm, it looks really sleek and modern - though does however flimsily wobble a bit if you knock into it. If you're not happy with the audio quality then I'd suggest a Sony 2.1 or 5.1 kit because of the Bravia Sync feature; ours switches on with the TV give or take 5 or so seconds.
All in all we're pretty happy with this TV. What I will say is that I haven't review the 3D feature simply because of the cost of 3D glasses which is close to £50. Manufacturers seem to be making a big deal over 3D technology whilst killing it off at the same time in this regard. Further, with all the crosstalk and issues I've heard about, I'd rather avoid it anyway ;).
Summary: Sony will be hard-pushed to improve on this picture quality until OLED technology arrives.
