I also do programming and am fairly used to the terminal, and I still have a headache when thinking of going back to linux, because even when I want to do something as simple as watching netflix on firefox I had to go through a maze of troubleshooting via the terminal to get the correct packages installed. I can't imagine what someone who isn't tech savvy who tries to switch to linux would do.

The user experience on linux and its distributions just aren't there for the everyday user, and until they are, windows will always be the preferable choice because it actually works. You don't have to end up having a dispute with it on some arbitrary software download because it doesn't quite like it, and have to wrangle through many software alternatives that aren't always available or even anywhere near feature ready because they aren't available on the platform.
