I don't like your analogy much because Windows makes me much less efficient, not more. Everything is more hassle, getting the right tools is a pain, etc. I code primarily on OSX and even though I have PyCharm, I find I go much faster with vim. Yes I am old.

In any case, I love my fountain pen. Not expensive, just a Pilot Metropolitan. I don't have the hand stamina that I did back when I had to handwrite practically everything, so I really appreciate the effortless experience of using a fountain pen.
