You have to remember that "engineering" isn't just "software engineering" or "web development". The vast majority of the engineering world does not use Mac/Linux. There are countless major engineering tools that only exist on the Windows platform and this has been the case for decades.

None of what I said is to imply these platforms are inferior in any way. We use both Mac and Linux. I prefer to do web development work on Linux because, well, you are working in exactly the environment you are going to deploy on and tools like PyCharm work great under Ubuntu. Outside of that, yes, doing web dev on a Mac is the next best thing. On Windows I always have to run an Ubuntu VM, no point in jumping through hoops to make believe you have a Linux environment, a VM works great.

Once you shift your focus to circuit design, layout, mechanical engineering, CAM and other high-power commercial tools, Windows is pretty much king. And, once you look at how smoothly Windows, Office, Exchange and other tools integrate at an enterprise level, well, it's hard to ignore how awesome of an environment it turns into.
