Years ago, Microsoft had a bold vision for the future of computing. It would be a tapestry composed of tiny squares. Each square would represent an app, a game, an experience of some sort, and you’d be able to just reach out and touch it. Or, if you already knew what you wanted, you’d be able to simply speak a name, and have the object of your desire materialize out of thin air — regardless of whether you were using a smartphone or lazing in front of a TV set.
That’s the vision Microsoft was building with Windows 8, with Windows Phone, and most intriguingly, with Xbox.
