Well... to be honest... it's also "up to Apple", because if Apple decides to stop supporting users of professional applications such as Revit, Ansys, Robot Structural Analysis, CYPECAD, Catia, SolidWorks, Tekla Structures, and an endless list of professional engineering applications... then, well, you can say it's "up to Microsoft", but the thing is that Microsoft is not losing these customers. It's Apple who loses them.
Forget seeing the Mac in engineering universities. You'll see iPads, but no Macs anymore.
