But if we accept "patentable" as a proxy for "invented", then obviously Apple invents a lot.
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).
We had this system for most of human history. It sucked. A decade and a half of exclusivity is a fair trade to avoid it.
