iOS is just as confusing as Android. Its a matter of which one you use first or regularly. Just as Linux is confusing to non-linux users.
Also. Android works on the dodgiest mobile hardware available to mankind. Something not a lot of HN users seem to know - from tractors in farms to research equipment in the arctic. I dont know about space, but if we are going to use a modern OS on space craft - I'm willing to bet it will be an android fork.
