Seems like QNX was hiding in plain sight as a car os and a mission critical os for other devices.

I wish we could get it's competitor TronOS to make a similar desktop version --- the demo of it displaying multiple video windows on an 80186 was jaw-dropping --- a shame the U.S. Trade Commission quashed Japan's Ministry of Education's plans to roll it out nation-wide in schools from elementary up through graduate.

There are tons of proprietary RTOS/microkernel products on the market. It's not so much hiding as it is crowded-out.

  • And none of them can hold a candle to QnX. I've used a whole raft of them and QnX stands heads and shoulders above the competition. The consistency of the implementation is extremely impressive.

I think the market is moving to "mixed criticality" so you can use Linux for your entertainment system but then also use a proper RTOS for the car stuff all in the same SoC.
