Zenity is very limited in what it can do though. You slam into the limits with some pretty simple requirements. Plus it spits out an annoying warning about parentless modal dialogs every time you use it. That said I've used it quite a lot because it is installed by default. If you can't guarantee that anything has been installed on the system or that you have an Internet connection it is incredibly helpful to have a simple GUI system available to shell scripts by default.
