QNX was/is simply amazing! Talk about an OS that should have utterly destroyed DOS and all other CLI-based OSs. I first encountered it at an oil-terminal company I worked at in the 80's and couldn't believe the features packed into such a small footprint. It's real-time event handling was top-notch, and it was stable as all-hell...in a sane world it would have dominated the market.
