First, let's not pretend that many Mac users haven't always had a heavy reliance on Windows and Windows applications. And ever since Apple moved the Mac to the Intel platform, that need has turned into a frenzy, with Mac users now able to choose between both virtual (Parallels Desktop, VMWare Fusion) and physical (Apple Boot Camp) solutions for running Windows applications on their Macs. Increasingly, Mac users are working in Windows and, I feel, understanding the benefits of using Windows instead of Mac OS X. Thanks, Mr. Jobs, for making that happen. No, really.
But as is the case with Apple's deceptive “Switcher” ad campaign, going from Mac OS X to Windows doesn't have to be a one-way street. Indeed, my suspicion is that very few people have actually transitioned completely from Windows to the Mac. I think most of them are using both environments, instead, and picking the one that makes most sense for what they're doing at the time. And as it turns out, moving to Windows from Mac doesn't have to be total and irreversible. Using the aforementioned solutions, Mac users can move back and forth between the OS X and Windows environment. It's the best of both worlds.
