I'm not quite sure which F8000 thread to post in, but since this is more popular I'll share my initial impressions. I just got back with the 55F8000, went through the setup menu, played with the remote and the Smart Hub, and then put in Prometheus 3D. This is replacing a Sony HX850 which I just returned due to vertical banding and a lot of crosstalk with 3D content.
Setup was a breeze, quick and painless, and it has easy tutorials to guide you through voice and motion controls. Those controls feel like gimmicks, however; I won't be using them often. As many of you probably already know, the only remote that ships with the television is a touchpad clicker. It makes me long for a regular remote, as I haven't found a way yet to simply scroll through menus and items with regular buttons. Instead, I have to make long swiping motions. That can get a tad tiring. It's not a huge negative, though. It's actually quite a sleek remote that's somewhat fun to hold and use despite it taking longer to get where I want to go.
The television itself is also quite sleek, with barely any bezel. The stand is wide but also quite minimal from a field of view perspective. I particularly like how may of its inputs are downward facing with a cover that can hide that section of the back, as well.
I haven't spent too much time with the Smart Hub, but right off the bat I enjoy it a great deal more than Sony's Entertainment Network interface. Everything is laid out well and navigating it is smooth. When you first start it up, though, it appears that it downloads all the apps instead of just shipping with them pre-installed.
So how does the image compare? In 2D, the picture is notably more detailed. Blacks are absolutely pitch black and there's no flashlighting or clouding to be found. It's a stunning image in Movie mode, even before any calibration. The television ships with four pairs of 3D glasses, all of which are lightweight and comfortable. They're a little loose on me because I have to put them over a pair of prescription glasses, but they're otherwise much more manageable than the bulky Sony PlayStation 3 3D glasses I previously used. Best of all, there's little to no crosstalk at all, whereas with the HX850 I could spot faint (or sometimes extreme) ghosting in every scene. It's also quite a bit brighter. 3D that I've previously experienced tended to have some headache inducing blur when the camera would pan, and thankfully there's none of that with the Samsung. Part of that is likely due to frame interpolation, which cannot be disabled when in 3D, but it's not the same kind of jittery motion smoothing I've seen with other sets.
These are just my impressions after spending 30 minutes with it. I haven't quite calibrated it yet aside from lowering brightness, contrast and the backlight, but I'm already in love. Blacks are deep, the image is crystal clear and gorgeous, and the 3D is so much less frustrating to me than what I experienced with the Sony HX850. I'll continue to give my impressions as I spend more time with it, but if anyone has any questions, ask away and I'll try to do my best to answer.
Edit: I'm a little further in Prometheus now, and the television's picture is still awesome, but I have to comment on one scene. When they enter the dome for the first time, David finds and starts interacting with a panel on a hallway wall. Partly due to the clarity of the image and partly to the motion smoothness going on, that scene looks absolutely real. It didn't look fake or like a soap opera. It looked like he was actually there in front of me. Amazing.
