As far as driving OSX from the keyboard... yeah, it doesn't go out of its way to teach you how, but there are some pretty deep keyboard shortcuts. Of real note is readline, which is built into every text box. You can use emacs/readline shortcuts everywhere, and because of the ctrl / cmd separation it doesn't interfere with the basic shortcuts.

I've been using Windows 10 more and more over the last 2 years. Its fine. For the first time in a long time I don't feel like Windows is slowing me down, especially now it has sub-system for linux. Its still annoying that processes can lock access to files... but thats small potatoes.
