Ok, well thank you for the clarification, as far as it goes.
What I am really looking for is a sort of score card, showing which major bits came from Apple, Microsoft, or someone else entirely (such as, per your explanation, USB and PCI). Globaljustin mentions Apple leading design innovation, which as far as I'm concerned goes without saying, but is somewhat beside the point. My interest is more in technology -- for example, after all the TRS-80s, PETs, DesqView, Windows on DOS, and OS/2, I remember being delighted with NT 3.1 when it first came out, as it was the first desktop OS that felt like I was using a real computer (i.e. nice, smooth multitasking). But Microsoft didn't invent decent multitasking, there was Unix of course, and IBM had it in MVS for years (I never used Multics, wasn't it the first decent one?).
In summary, who really out-innovated who?
