I suppose anything that was as advanced as the Amiga (hardware and OS) will always leave a mark yes and that is part of it. What makes it magic is that I lived those times as they happened. What makes it sad is that I know for a decade, or more, what we were forced to use inferior products (Wintel/MacPPC/Mactel). And all due to the disappearance of Commodore and incompetent useless people involved with the IP in later years.
i guess those three aspects of the package, living it and the fact inferior products won out and still exist today is what makes the Amiga memorable and gives it some kind of magic I guess.
