Solaris, BSD, HPUX, hell even stripped-down Linux installs (though sometimes it exists and is just in a weird path). Occasionally I need to bootstrap an OS installer and they never have Bash.

By default I write Bourne, and if I need the extra complexity/speed/etc i'll switch to Bash, but it's pretty rare that I need to use Bashisms.
