First home computer with:
multimedia capabilities, autoconfig "which is now known as plug and play in windows", multiple draggable screens in various resolutions at the same time, Autorun and probably loads of more...
Also worth reading into the amiga custom chipset aswell, as there was quite a bit of innovation there.
I find it sad that microsoft get alot of the fame here, even though the Amiga had alot of it over 10 years earlier..
