Incidentally, I've been using fish for a while, and it's really nice. Coworkers wandering past while I'm working have been known to stop and state; the fish autocompletion/history magic is really impressive if all you've known before is the standard bash Ctrl-R stuff. And once you get used to it, and huge productivity boost, especially if you work a lot with tools like HTTPie.
(And while compatibility with tools which expect bash gets brought up a lot, I've had zero issues. YMMV.)
