I've had mine since launch with three games Crimson Dragon, Battlefield 4, and Dead Rising 3.
The console itself I like, the look is pretty cool imo. It has little likeness to a VCR(alot of people thought it would). I don't like how its gloss and will attract dust like a mother fucker, also the main USB port is on the left side which could be frustrating in the future. My main complaint is that the UI is awful, its hard to navigat, has terrible load times, and its only customization options are to select from ~15 colors. Last thing about the console itself is that it generates a frightening amount of heat, one reason that its so big is for ventilation and I will say the system has still yet to crash on me with 7-15 hour sessions of play.
The controller is... hard to explain. I prefer the 360s but that could just be habit, when you pick up there is no adjustment time from the 360 you know where everything is and what everything does. The thumb-sticks are a thousand times better, the grips are great and they seem more precise. D-pad is better, but I haven't played a game thats super heavy on the D-pad so I can't say too much about it. Everything feels more condensed, and I think whether or not thats good is very person specific, but I don't like it. If you've read some reviews for the controller people will bash the bumper, I don't really know why, they are bigger and easier to click if you have large fingers. They could be more difficult for kids, but I'm not sure about that. The bumper area is gloss, just like the console and get dirty easily, the thumb-sticks also do this but you won't care unless you get really bothered by that sort of thing like me.
The Kinect is good, people say they won't buy it unless they can get it without the Kinect. You want the Kinect, its a good thing, but this is coming from someone that doesn't really care if someone is watching him. The best part about it is how I no longer have to press anything to sign in, the Kinect knows who I am and after it booted it takes up to 7 seconds to sign me in.
The games I have are good, but BF4 is glitch as hell right now. Dead Rising 3 deserves to be fighting GTAV for Game of the Year it is the best game I've played in a long time. Crimson Dragon gets boring, but its a good way to waste five minutes. I should say before I end this post that I'm stupid and shouldn't have bought a launch console, I'm happy I did and I love my Xbox One. That being said, if your shelling out the cash I suggest waiting until after next year and then picking one up.
