Truth!I can't wait to play my Xbox One games on any screen in the house, at any time, with a real controller...priority big-screen seating can be hard to come by at my place. Even more multi-tasking abilities will be nice too when the big game is on. Better yet, I don't need to buy anymore Xbox One's. Oh, and it's free! No extra handheld or mirroring device needed.
On the Surface (hint, hint) this looks like a blatant attempt just to get you to buy some cool new Windows 10 capable gear. However, if you really think about it, it's an even more blatant attempt to get you to buy into the overall Windows ecosystem and control your total screen time.
Seriously, I think most of us are already there with one PC/Phone/Tablet OS or another, might as well game on it! Did I mention free?
Also say you're watching a playoff game and want to play a single player title, now you can do both, not worry about needing PIP or anything like that. Biggest benefit will be for those who have to share a TV.What's the practical application of this? I can't think of a scenario where I would want to do this.
