The braille is for the sake of literacy. Reading instead of always listening. Personally, I would prefer to read something instead of listening to audio all the time.
Braille displays are also used with iPhones for folks who are dead-blind. I trained a dead-blind guy to use his iPhone with a focus 40 braille display. He is great with it now. He texts, emails, looks up resturant menus, and arranges his own transportation.
