I strive to use bash as minimally as possible anyway, I don't quite see the point of switching to zsh when I want to avoid doing things in the shell (rather than scripting or using cron jobs or similar).
Why would people want to use an alternate shell? How much do you need to be constantly sat in the shell typing out the same commands rather than either scripting them away or doing something within a text editor?
It's not that I don't like it, I just don't see the purpose of remaining there once I'm done writing a script or whatever. Your use-case is one of those where it does makes sense to do that.
