Really impressed by spacemacs  so far.  I started out with Emacs back in the day.  Switched to Vim at some point.  Spent the last 7 years or so using Visual Studio with the fantastic VsVim plugin.  After a while I began to see Vim more as a great set of keybindings, not so much as a program to proselytise in its own right.   Most text editors will have a Vim keybindings plugin.  Now, after moving to new work and away from the Microsoft stack, Spacemacs is seeming like a great system – very very thorough Vim bindings support, but with a very powerful and well-though out system underneath that.
