Aren't the stakes a little different with an iPhone that you have for picture taking and entertainment vs the systems that manage your trajectory and life support?
The fact that a handful of devices hasn't failed is hardly proof that they can't. Hell, I've driven thousands of times and never actually NEEDED my seatbelt.

Again, that's not what I'm saying. I'm just challenging OP's assertion that any device with no radiation hardening will "immediately" fail, which clearly isn't the case with these devices. That's not me saying that radiation hardening isn't needed, quite the opposite.
