I have been using Windows and OS X side by side for more than a decade. At my job, we use PCs. For my freelancing jobs, I use mac. I am a professional graphic designer BTW. I use the same set of softwares (Photoshop, Illustrator, Indesign, Cinema 4D) on both platforms. The biggest issue that I have with windows is lack of previewing of my files. I have a thousand photoshop files named similarly that I need to view instantly and not open up Bridge or Photoshop to go through them one by one. There's no way to do that natively on windows. Also, explorer is faster than finder and finder isn't perfect but explorer just doesn't feel as good. As for settings, just hitting the start button and typing works, no need to type in the search box, but you have to know what you are looking for. Its not as simplistic as OS X. Also, spotlight is something that I miss on windows.
