I'm guessing that QNX will soon face a run for its money as iOS and/or Android start seeing use in devices besides phones and tablets. A common UI experience from phone to tablet to automobile controls/navigation would be something consumers would appreciate.

I'm going to go out on a limb and predict that iOS and Android will never be running nuclear reactors.

I think you're right for things that have moderately interesting interfaces, but do you really need android in your thermostat? Keychain? Other random device? Qnx in card isn't just your maps and stuff, it's your braking system, crash detection system, etc.

I don't think you understand what QNX is or where it's used then. QNX will not be seeing serious competition from Android or iOS anytime soon in the domains it has locked up - ones which require hard real-time.
