The only standard shell on Unix is the bourne shell, and having things break because someone ignorantly hardcoded bash without using any bash-specific extensions is really annoying.
I agree it's worth the time to find a shell you like and customize it, but that's not a good reason to pick bash.
I don't remember the last time I touched a unix other than Linux or OSX. I don't expect to anytime soon either. It's not out of prejudice either, that's just what people seem to use for most things now. I'm not really willing to sweat hypothetical portability issues between the shell scripts I write for my Linux environments and some potential solaris/bsd user down the road either.
I don't care what you use for your own shell scripts* , I just have a problem with recommending that someone use bash because "it's everywhere".
I think people are better off coding to a standard shell (as necessary), and otherwise using whatever shell makes them happy for day-to-day use. bash isn't actually the former, though, and it has strong competition for the latter, so it's probably a bad compromise.

Sure. I'm just saying that, in my own case, switching from zsh to bash has meant that instead of worrying about making sure that zsh is installed and up to date on all my systems and that all the various addons and plugins I used to need for zsh are available, I just have to make sure my .bashrc is available. And even if it isn't I don't lose much. So I get a functional, familiar environment in all the cases that matter to me with no extra hassles.
My favored point on that continuum is to skip the 'various addons and plugins' and just apt-get install zsh on all my machines. To skip zsh altogether seems like throwing the baby out with the bath water. I tend to think of it as a better bash implementation.
Yeah, and while I don't use zsh, I keep all my emacs config in a git repository with my other dotfiles. That plus apt-get / pkg_add / etc. seems to solve the problem nicely.
No, it isn't. Here's the Unix spec (http://www.opengroup.org/onlinepubs/007908799/), search it for bash and you won't get anything. That's a Linuxism (http://www.google.com/#q=linuxism), but it's not even on every kind of Linux.
