So, windows is used on my mac pro for a variety of purposes but the biggest is probably games and applications which need a windows platform. With windows 10 there is so much under the hood performance based code being updated that we will need parallels to step up the integration of hardware and allow for better, faster graphics rendering or some of us will have to turn to bootcamp again or try VMware which seems to have tighter performance integration. I personally will be migrating all my gaming to windows with windows 10 Xbox integration.
