Thanks for this, I decided to run through the setup again for Kinect using the troubleshooting section as I initially just placed it where the 360's Kinect had been. It was working fine but I wanted to see if it would prefer a different angle. Going through the test and it recognizing my floor, it then wanted me to tilt it as far back as possible. So I expect it to work even better now.
It has been useful for me too, especially this.
After a week with the console, these are my quick impressions.
Controller: The best Xbox controller to date, by far. It is obvious it has been made for the mainstream public, for men, for women and children, because it is light, much lighter than the Xbox 360's gamepad and fits most hands well.
Interface: Lots of multitasking, many things can be happening at the same time and some excellent tools. However, it is very green. At this very early stage they are listening to feedback.
Good idea 'cos there are things that are worse than they were. Especially the parties. They worked fine the first couple of days but now parties aren't as straightforward as they used to be on the Xbox 360.
I love the new messages interface, because I have all my messages organised and displaying horizontally. That's fine and dandy, but again, getting to the messages isn't as straightforward as it used to be.
Xbox Live: It has been working nicely for the most part. But I gotta admit I haven't tried the games where the netcode is the most important thing. The cloud is showing some nifty tidbits about how things might be in the future.
The console: It is very elegant and very silent. In fact the power brick is louder than my console.
The voice recognition makes the interface and games derive benefits from it. BF4 is more fun when you can issue voice commands without touching a button (Engage!), so is Ryse, NFS Rivals and FIFA 14.
Some friends with kids mention that their children go all crazy over voice commands, Xbox show my stuff, Xbox record that, Xbox turn off --> yes, etc etc etc. The whole integration with the TV and multitasking means that the future with these new consoles is now.
The console also has Xbox Video, with a huge library of movies (300.000, second place in the world).
As an early adopter I know some things can only improve. In addition, the console shows a great potential.
