I was on the Windows platform for 15 years and moved over to Linux about 6 years ago. One thing I miss from Windows Server is that it was very stable, updates never broke anything. If you got any updates that is.
I think most people use Windows server because they are locked into Microsoft technology.
I switched to Linux, and most importantly open source technology - in order to get out of the Windows ecosystem. I switched from an ASP stack to Node.JS, but it feels Microsoft is still stalking me, buying NPM, Github, releasing their own JavaScript flavor, releasing their own "open source" software bundled with proprietary add-ons, meanwhile suing Linux users for patent breach.
