I'm not sure how many serious devs use LightTable (although I'd be interested to know!). I keep it handy for writing little scripts (in Clojure, Python or Javascript) that benefit from the interactive style, but I do most of my actual development in Vim. I tried emacs, but I just couldn't stick with it, and the fireplace vim plugin is really great.
