You can use a Mac for standard "productivity" purposes (because it runs Office). You can use a VM, which are now quite mature, if you require some Windows-only app. Mac integrates well with MS Exchange now (for corporate e-mail and calendaring). Beyond mere compatibility: The build quality of Apple laptops is excellent, which is a positive incentive to move over. And, most importantly, if you've personally bought in to the Apple ecosystem (iDevices, iTunes), or use a work-provided iPhone or iPad, then you have an incentive to actively move off your Windows system. They're not being used as servers, or for open source apps. Put yourself in the shoes of some "knowledge worker" at BigCorp, contemplating what his/her next "seat" will be. You'd have such a choice every ~3 years, so there's a delay between when the choice is obvious and when you can actually do it. I don't think Apple cares hardly at all about this, BTW. It's more of a "rising tide lifts all boats" phenomenon -- a side-effect of their main strategy, which is consumer-focused and not enterprise-focused.
