I do miss Xmonad-like window management, but windows does have shortcut keys that do a good enough job. Emacs works perfectly well. And Anaconda (https://www.continuum.io/downloads ) is actually a good native windows distribution of Python and Julia.
Cortana + voice recognition is actually pretty cool, I'm looking forward to hacking on it when MS releases the dev kit.
So far, windows seems to be an acceptable Linux. I will probably stick with it for a while, assuming I don't run into any crazy new blockers.
(I've been on Linux exclusively since 2001 except for a brief attempt to use OS X around 2009. That experiment was less than successful: https://news.ycombinator.com/item?id=1786930#1787411 )
