One of the biggest mistakes Microsoft ever made was when they decided to port Windows NT – which was initially designed to displace UNIX – to the same general consumer market as Windows 9x. [Disclosure: Microsoft is a client of the author.]
Servers and workstations have very different priorities than a typical desktop OS. So when they blended the efforts, the general user and consumer OS became too complex, and the workstation and server OS picked up consumer elements that made the result less attractive to IT buyers and engineers.
At WWDC, Apple appears to have announced they are taking iOS to where Windows 9x used to be and allowing the MacOS to mainly focus on their workstation products (they’d tried servers last decade and that effort ended badly).
