But those of us who think the entire idea of "patentability" is a joke in and of itself.

All these fuzzy lines behind this "who invented what" is a major reason I consider patents to be evil -- the entire system sets up artificial and harmful barriers keeping ideas from fertilizing each other and growing beyond our wildest imaginations.

(And as someone who strongly dislikes all things Apple -- but not quite as much as all things Windows -- I cannot help but observe that both Apple and Microsoft simultaneously deserve both more and less acknowledgement, all depending on how one looks at things, for their inventiveness).
