There are literally thousands of options for configuring your device in the Preferences app. Should we put all of them in front of the user's face the first time they set up their phone? How would they know those options exist otherwise?

Knowing that you can configure your phone's behavior should be a basic point of technology literacy. I know that it isn't at 100% today, but what percent of users are now going to have yet another forced decision to make before using their phone for the first time, just so a minority of technology illiterate users can be "educated".
