I may be wrong on this but weren't the fruit analogies originally meant to describe the difference between class based and prototype based languages and then it was extended to actually teach the concepts in a way that didn't work? I remember my professor using them to try and teach pre-standard C++ and when I pressed him to explain actual use cases I figured out he didn't understand himself. I have the feeling it was meant as a bridge for lisp programmers moving to class based languages but that may be because we learned lisp first. Anyways that context is the only place I found value in it.
