The biggest pull keeping people on Windows, outside of shear inertia, is content creation and gaming

You're forgetting the huge and much more lucrative market that is businesses. We literally can't switch away from windows because every single piece of engineering software we use only exists for windows. We can't program anything, configure anything, deploy anything or service anything if we're not running windows. Oh, a VM solution you suggest? wrong!, because the drivers needed to interface with the hardware are wonky as hell as is but inside VMs it gets the job borked half the time making my job unnecessary frustrating.
