I'd recommend this TV for anyone looking for a step up from smaller LCD screens or wanting to buy their first Full HD Television. The picture quality is excellent: Simply stunning. Standard def clarity is perfect for such a large screen - no complaints there, but it's when you move to HD pictures that will show the sets true potential. Colours are perfect (with a little tinkering), motion is smooth and i've noticed no bleeding on the edges of the panel - so all good.
Blu-ray 24p movies run smoothly from my PS3, I havn't noticed any judder (maybe a miniscule amount more than some high end, much more expensive screens - but hey this is under £800 so its certainly not a complaint). I can't stress how good the picture quality is for an £800 46" LCD - it's awesome.
I have a PS3 running to the TV through a Sony HT-IS100 via HDMI, and SkyHD direct to the TV via HDMI. (SkyHD audio via optical to the HT-IS100) No audio sinc problems at all. I can't really vouch for the built in sound, but if it's anything like my previous samsung (LE37R87) then it's fine for everyday use, lacking in bass and clarity for movies.
PROS:
Great build quality
Nice solid glass stand
Incredible value
Perfect HD picture
24p (True HD) makes a big difference
Good remote - fast
CONS:
Weighs a ton - almost impossible to attach the stand alone
Box was flimsy - Not enough packaging!
On board speakers are a a bit ribbish - but no more than usual
They still havn't added a button to switch between HDMI inputs -(You have to scroll through the source inputs)
