I hope you were joking about that. Windows doesn't have the software I need, thus why I run OS X.
No joke, no joke at all.
In my line of work I need to interact with clients and their Excel files, Word documents, Powerpoint presentations, databases, forecasts, etc, and each have their own nuances and issues when created/opened/edited/saved on OSX vs. Windows. If in your profession OSX is the norm, that's cool, you have what you need and can interact smoothly with the rest of the 7%'ers running that OS.
And if you find this unbelievable, please remember, of the 93% of the world's PC's using Windows, 75% are running Windows 7 and Windows XP. And that's no joke. Compatibility between operating systems and their associated software therefore has to be compared to conditions in 2001 and 2007. That's what's going on in the real world. Outside of Apple, all the products you buy, all the food you eat, all the banks that hold your money, all the restaurants you eat at, all the trains you ride, all the hospitals you are treated at, they're all run in significant numbers on old versions of Windows. It's cool for a student or an artist to eschew Windows and commit to OSX. But here in Big Business America, that's suicidal.
