A colleague is using it and I had a look, but it seems kind of weird because it doesn't seem like Emacs any more to the point where I couldn't easily do Emacs stuff with it.
I've been using regular old Emacs for about 20 years. For those more familiar with Spacemacs, how hard is it to accomplish some of what it does, or transition to a more normal Emacs setup once you get to like Emacs?
Edit - this is just out of curiosity. I hope to use Emacs for another 20 years at least :-)
