In a move that only further closes the gap between the quickly merging Windows worlds, Microsoft has shuffled itself around in what Steve Ballmer terms "a far-reaching realignment of the company."
More specifically, Terry Myerson—formerly of Windows phone fame specifically—will be heading up the entire OS department, including Windows and Xbox software and systems. Additionally, Julie Larson-Green will now be heading all hardware development, a turn from her previous, strictly Windows position.
According to Ballmer, this shakeup is being implemented with the hopes that it will "enable [Microsoft] to innovate with greater speed, efficiency, and capability in a fast changing world." While all of this is significant, none is all that surprising considering the rate at which Microsoft has been taking steps to turn its lineup into a single, cohesive ecosystem.
In Ballmer's memo to Microsoft employees, he explicitly describes his grand vision for an eventual Windows singularity of sorts:
We will strive for a single experience for everything in a person’s life that matters. One experience, one company, one set of learnings, one set of apps, and one personal library of entertainment, photos and information everywhere. One store for everything. Microsoft has the clear opportunity to offer consumers a unified experience across all aspects of their life, whether the screen is a small wearable, a phone, a tablet, an 85-inch display or other screens and devices we have not yet even imagined.
