I still don't see any reason to not switch to Linux from MacOS. I love iTerm and Alfred and especially the unified keyboard shortcuts. I also thoroughly enjoy the MacOS window manager although not as much as I used to (I can envision a replacement). But there's just nothing Windows can offer me that Linux can't.
If you're OK with limiting your computer interactions to the 20th century, then yes, there's no reason not to run Linux directly. The most awesome thing about the WSL/Win10/Surface combo, though is that I get all the best features of Windows, including support for touch & pen, and all the best features of a real Linux box (which does make it way easier to keep your dev env like your deploy env.) I will never go back to a "caveman computer" that I can't write on to sketch and take notes in OneNote or similar apps. No Mac can offer that capability at any price.
