Microsoft has been pretty coy about showing off Xbox One’s user interface…until now, that is. Xbox’s Yusuf Mehdi and Marc Whitten demonstrate the One’s UI and its speedy multitasking prowess in the 12-minute video embedded above.

They mostly demonstrate features we’re already aware of, but seeing truly is believing in this case. Sit down in front of your Xbox One-equipped TV and Kinect will sense your presence, recognize you, and automatically sign you into your Xbox Live account. If your buddy’s with you too, no problem; Xbox will sign both of you in and you can switch between your personalize dashboard and your friend’s simply by saying “Xbox, show my stuff.”

The One’s home screen is pretty straightforward. The middle, main section is called Home and there is the space that shows you your most recent live session, whether that may be a game or an app. To the left of Home is Pins; this is a customizable space where you can pin and save your favorite and most frequently used apps and content for easy access. And to the right of Home is Store; this space is divided into various storefronts such as Games, Movies & TV, Music, and Apps.

Multitasking on Xbox One, or jumping in and out of games and apps, is truly a breeze. In this demo, Yusuf and Marc are playing Forza Motorsport 5. Say “Xbox, go to Netflix” and the system will automatically pause the game and jump into the Netflix app. Say “Xbox, return to Forza Motorsport 5” and you’ll jump back into the game exactly where you had left off. It’s just as easy to switch to Internet Explorer, Hulu Plus, and any other app you might have installed on your console.

Also discussed are the advantages of having your games system tied to your cable box. With the One’s HDMI IN port you can hook your TV feed into the Xbox and browse and watch live TV through the system. So, when you’re watching TV now you receive Xbox notifications and jump directly into a game when an invite is presented. You may also receive a Skype call when you’re watching TV and you just as easily pause your programming to initiate a video chat. Skype on Xbox One boasts a 1080p HD widescreen picture and Kinect will smartly track your movements as you move around your living space during a conversation.

Lastly, two new features of Xbox Live are demonstrated here. With Game DVR, gamers can record their gameplay, edit it and share it with friends via the Upload Studio app. You can even select picture-in-picture mode which will record your gameplay as well as instruct Kinect to record you and your narration as you play. With One Guide, you can browse your TV channel lineup by saying things like “Xbox, what’s on HBO” or “Xbox, what’s on ESPN.” You can also create customized favorites lists within One Guide with your apps; for example you can make it easy to browse Hulu Plus’ latest offerings right inside One Guide without having to jump into the app itself.

Side note: Speaking of digital entertainment apps, Microsoft has announced the full list of said apps that will be available on Xbox One at launch and you’ll find the full list after the break.

But words can only say so much. Hit play and discover just how fast and intuitive the new Xbox really is. Xbox One hits the market in just 12 days on November 22.

Update: Yusuf is back to demo another Xbox One feature not covered in the extensive video above. It’s called Snap and it allows you to “snap” or pin an app to your screen while you’re doing something else. For example, while you’re playing Forza you can say “Xbox, snap Internet Explorer” to pull up the browser  and view a website while you’re playing the game. You can even say “Xbox, snap TV” and you can watch live TV while you’re racing. It’s multitasking for the hyper-active generation. Watch it in action after the break.
