I think you probably don't know emacs if you think no one should find it useful. I highly recommend you give it a go. It may not become your main IDE, but I can guarantee that you'll find it very useful for a multitude of tasks, like a lighter text editor, quick REPL, RSS feed reader, binary file reader, org mode (like an organizer of tasks/notes/literal programming etc), magit (the amazing git client), grepping and navigating easily between search result files... and so many other things.
