Deeper Xbox integration
For all the talk about pushing a seamless “One Windows” experience across its sea of devices and making the Xbox One more than just a gaming machine, the console sure seems to be the black sheep of the Microsoft family.
Windows 9 could bring the lost lamb back into the fold. For example: Microsoft could install Xbox Smartglass on your Windows devices by default if your Microsoft account is tied to an Xbox profile. Or what if you had the ability to manage your Xbox account or message Xbox Live friends within Windows? And, for all that is holy, Microsoft could enable some sort of AirPlay-like capability so that you could cast media or share your display on the big screen with minimal fuss—and not just the stuff you bought from the Xbox Video and Music apps.
