> QNX is used in vehicle infotainment systems no? Where else?

A bunch of similar embedded systems. And blackberry, if anyone's still using them.

I went to a conference at GE Research where I spoke to some QNX reps from Blackberry for a while. Seemed like they were hinting that some embedded computers in some of GE'S aerospace and energy stuff relies on QNX.

It was used in my old toyota avensis from 2012. The infotainment was so slow you could measure performance in seconds pr frame instead of frames pr second :)

In the end, all I could practically use it for was as a bluetooth audio connector.

I've worked with it in industrial automation systems in large scale manufacturing plants where it was pretty rock solid. And I'm aware of it's use in TV production and transmissions systems.

Cisco routers running IOS-XR, until relatively recently.

Railroads/Positive Train Control, emergency call centers, etc. QNX is used all over the place. If you want an even more impressive Microkernel RTOS, then Green Hills INTEGRITY is a great example. It's the RTOS behind the B-2, F-{16,22,35}, Boeing 787, Airbus A380, Sikorsky S-92, etc.

"Even more impressive" in what way? I haven't used INTEGRITY but used the Green Hills compiler and debugger extensively for years and they're easily the most buggy development tools I've ever had the misfortune to use. To me the "impressive" thing is their ability to lock safety critical software developers into using this garbage.

Routers, airplanes, satellites, nuclear power stations, lots of good stuff
