I've been using the RCs for a while. It's a lot better than previous versions of windows I've used. But I am an outlier, I need my commandline tools, and I need to be able to explore and hack a bit on this and that. Things I like about the new windows: It has great integration with thumbprint It comes with powershell (although I still disklike powershell compared to zsh or other shells, its a step in the correct direction) It's interface is smooth (with a caveat later) Things I dislike: The new interface stinks when configuring anything. For example: Click on "Configure printer" a window will pop up. DO NOT CLICK OUT SIDE OF THIS WINDOW or the operation will stop! Cortana is stuck because of the previous interface bug (If you set up a new account and are fast with mouse clicks, it will be re-setup, otherwise it just sits there judging you and your stupid human inability). I still like linux because of package management, which is something the windows store seems to hope to solve.
