It is, until it isn't. If you deal with people in the mainstream business, legal, healthcare, etc. worlds you'll run into issues. If you work in one of those mainstream fields, you'll find yourself quite limited if you're running anything but Windows. None of your corporate/enterprise software will work unless it's web-based (which is more and more the case, but certainly not always).
Until one gets to install into a NUC with an UEFI that doesn't get Linux, despite all magic incantations on hard disk setup, or a wlan router whose connections keep being dropped.
