It didn't help that graphics on the PC were absolutely terrible. IBM's monochrome monitor was beautiful, but text only. Their color graphics card had one of the worst interfaces you could imagine short of setting pixels one-by-one over, say, a serial port.

The PC world would have been a far more interesting scene if IBM had consulted with or purchased technology from someone like Atari or Commodore.

Don't get me started on audio.

IBM really blew it. Arguably, we're lucky they did, given the market opportunities that they created as a result.
