OK, I've given it a good whole year. I'm calling it: zsh's supposed benefits don't justify the move from bash. I'm gonna get the latest bash and go back to using that.
@erinrachel @carlton maybe I'm a generic shell user, but I don't see any meaningful difference between bash and zsh.
@mike @erinrachel little weird differences that pop up when you’re not looking. Just not worth it, because as you say, there aren’t significant actual differences
