Please don't forget that the Amiga was in fact created by a rebellious band of developers who first called themselves Hi Toro and the machine "Lorraine".
The now late "father" of the Amiga, Jay Miner was originally at Atari, where he designed the legendary Atari 2600 and some special chips Atari used for many machines (the Pokey chip for example). He left when Atari's leaders refused to fund a research project for a 16-bit computer. Jay found some venture capitalists and hardware developers and started work. After various difficulties and strange happenings, they created a piece of history which Commodore bought and in a way ruined.
