I also agree with koaftder!
I beleive the simple beauty of the amiga was a blending of chips that could get the job done and an OS that allowed you to get the job done without fuss
IFF was the corner stone to this! AmigaOS recognised what file it was looking at, did what was needed for that file without the user having to predefine a role based on some silly file extension etc
And Icons... I really like the Amiga Icon system :-)
