One thing that's going to set the next-gen consoles apart from current-gen is the huge focus on multi-tasking. While the current crop of consoles support a multitude of different apps, switching between them isn't too elegant, and one might cancel another out. A new video showing-off multi-tasking on the Xbox One proves that we'll be dealing with true multi-tasking there. You might even begin to confuse it for a PC.
Thanks to the Kinect sensor found on the Xbox One, users can issue voice commands to get things done. In the below video, we get an idea of the potential here: "Xbox, go to Pacific Rim", "Xbox, go to Activity Feed", "Xbox, record that", and "Xbox, watch TV" are a couple of great examples.
Where the multi-tasking really begins to feel like a PC is when a command like "Xbox, snap Internet Explorer" is issued, where, just like in Windows 8, you can snap an app to the right or left side of the screen, allowing you to continue watching your show on the opposite side, or use some other app.
Overall, multi-tasking on the Xbox One seems to be intuitive, and if it lives up to what's seen in the video, no Xbox One is ever going to find itself lonely given the amount of talking their owners will give them.
