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.
Seems like QNX was hiding in plain sight as a car os and a mission critical os for other devices.
Blackberry OS 10 was also running QNX under the hook afaik.
There are tons of proprietary RTOS/microkernel products on the market. It's not so much hiding as it is crowded-out.
