You've gone completely off in a different direction!
I KNOW what the Amiga is (I've been an Amiga user since 1991).
I KNOW what a PC is
I know there are aspects of Windows that are taken from WB and MACOS, other things that you think are taken from WB are simply common sense things that all gui based operating systems would at some point have been included simply because it's common sense.
Organising Icons on a desktop is an example of something that is common sense.. Amiga just did it first!
Also the Amiga was NOT initially developed as a games console/machine.. it was originally developed for more serious work. It just so happens that Commodore repackaged and slimmed down the a1000 and released the a500 at a much more affordable price.. the result is well known!
