On the flip side, I'm a Mac user (with a C#/Windows background) who really likes Windows 10. I've been on the fast ring for updates since day one on all my computers and been delighted--not a word I use lightly--with the updates and the stability of the whole thing.

It won't be my primary OS--nothing without zsh will be, and Cygwin isn't sufficient--but I really enjoy using Windows computers again, which I honestly never thought I would say after I switched to OS X.
