Pros: full 4k @ 60hz, motion controlled remote, the internal speakers are amazing, nothing compared to a 5.1 system but for built ins they impressed me, and they get really loud without distortion, excellent soundstage.

Cons: have to do some digging and tweaking to get settings right, then even once you have them set up they dont stay where you put themsome times. until you figure out how to get the setting to stay, sometimes the settings are inaccessible for no appearant reason(it seemed). for instance to turn game mode on or off you need to hit menu button then go to menu, select the system tab, scroll down 2 pages, hit general and then game more option is at the top of the list, BUT, sometimes game mode is not selectable and it says function not available or something... I remedied this by changing the input device type from pc to generic i think... also, getting the max resolution to show up on my computer was a 2 or 3 day battle that i won by swithing hdmi ports a few times. could be because of my pc though.
there are too few navigation buttons on the remote and its a slim remote but less than half of it has buttons on it. the point to click thing is way cool but sometimes i wish there were a forward and reverse button next to the play pause button instead of being forced to aim at a tiny button with the motion controlled remote.
virtually all of the sound options are disable under any sound mode other than standard. my unit had a little piece of debris under the glass that you can see against a light color its a tiny spec thats hardly noticeable but its there.

Other Thoughts: I use this tv as a pc monitor infront of my bed. the built in wifi and apps let me do some light browsing, and netflix/youtube, if i dont feel like powering on my rig. I love this tv. i would opt for the 240hz edition though as the 120hz get a little choppy with fast motion while watching film... you must turn it off and put it in game mode for pc gaming however, because the input lag is huge with it on.

Pros: - Its curved - reduces glare and really looks nice. Especially if you are sitting close to the screen for gaming
- Exceptionally crisp
- I was really shocked out the amount and results of using the included settings. When they say smart TV they mean it. It connects to WiFi very easily and then boom you're streaming Netflix if you want.
- Best looking TV i've ever owned and better looking than my monitors, it is 4k after all.
- Included features are more than i expected and the number of ports is great.

Cons: - I didn't find any that are the manufacturers fault.

Other Thoughts: I got this for gaming. This is my first 4k monitor. Switching to 4k and a 40inch screen at the same time is incredibly challenging. In hindsight I would prefer to have a 30inch monitor. I guess there is such a thing as big enough. That said - i am very pleased with this monitor and will be sticking to it and learning how to play on this display and resolution. The fact that i switched from my gaming laptop is making my change all the more challenging.

Pros: I am very happy with this TV or in my case monitor. I had no issues at all achieving 4k/60 4:4:4 with a 980 ti driving it. Picture looks great and I am not noticing any lag issues even with leaving PC mode on while gaming. I wasn't sure about the curve, but it is really growing on me. For $50 over the 6500 I figured why not. It does get you the very nice motion sensitive remote also.

Cons: Like many reviews state, this TV doesn't handle 24fps very well, the motion is not smooth. If using this as a monitor though, it doesn't really matter, the only problem is tweaking game settings since there is no single card that can handle max settings at 4k. Samsung's T&C's for using the Apps are overly intrusive.

Pros: Works great! gives 60hz under windows 8. Replaced 2 28" monitors with one of these and it is sooooo much better. using with a EVGA GTX 980 SC FYI

Cons: none really.
