This TV replaced an aging Samsung 52" 650 series...a fine TV in it's day. Well the D7000 blows it out of the water. The LED backlighting really brings the picture to life. I'm confident that this set is among the best of 2011, both in performance and aesthetics. Definitely one of its coolest features is its internet connectivity. Like many other brands you can browse through apps (Facebook, Netflix, Youtube, Hulu, etc.) but this is the first to have a full web browser...and assuming you have a solid internet provider, it's fast too! The only unfortunate thing about it right now is that you have to wait 10-12 weeks before you receive the full Qwerty remote, so you'll be browsing with unimaginable inefficiency (you're using the numeric keypad to enter web addresses)!
So far the only minor issue I have found is that sometimes there is obvious "bleeding" coming from the edges/corners when the screen is black. It doesn't seem to happen during movies, only during the transition phases, like when programs are loading or you're scrolling through sources. I have not tried the 3D yet so I can't comment on its quality.
In summary, a ridiculous amount of technology in a small and beautiful package; a near perfect TV.
