I've been looking into spacemacs, but I've found it to be a bit bloated vs. my personal config. It takes longer to start up, and sometimes just typing text in Insert Mode was sluggish (I imagine due to one of the autocomplete/typeahead libraries). That said, it has a lot of nice things and nice ideas. I'm undecided if I want to port my personal config to spacemacs, or just pull things out of spacemacs into my personal config.
