This is excellent. My grandma (89) uses an iPad and iPhone. She can use both these devices exactly because of the simplicity mentioned in the article.

1. Open app by tapping it.

2. Close it by tapping the physical button. (rip)

That's it. And that's why my grandma can use it. The first and only device she comfortably uses to this day.

People in our (tech) communities tend to overestimate a users ability with technology.
