During Microsoft's recent earnings call, CEO Satya Nadella stated that the company would "streamline the next version of Windows from three operating systems into one single converged operating system," relates The Verge.
"This means one operating system that covers all screen sizes."
This isn't the first mention of a one-OS-fits-all vision -- Windows Threshold has been in the rumor pipeline for months, if not years, after all. But, it is certainly the clearest. Microsoft's vision is simple: phone, tablet, laptop, PC, Xbox, whatever -- one operating system and one set of universal apps that work everywhere.
