The other way around might have worked. If Amiga became a graphics card company they could have leveraged a market that was several orders of magnitude greater in size. Imagine a PC but with the sound and graphics of early Amigas, instead of CGA/EGA + PC speaker. Look again at the article in my earlier post[0], specifically the graph[1]. No way was Amiga going to supplant PC compatibles as a business necessity in most middle-class households. But as GP mentioned, graphics card companies are still ticking along today.
> In 1985, Bill Gates wrote an amazing memo to Apple management. In the memo, he praised the Macintosh for its innovative design, but noted that it had failed to become a standard, like the IBM PC was becoming. He correctly deduced that it was the advent of inexpensive, 100%-compatible clone computers that was propelling the PC ahead, and that any defects in the design of the computer would eventually be remedied by the combined force of the many companies selling PCs and PC add-on products, such as new graphics cards
