I think it should auto update. My mom who has a iphone likes it because she plugs into her computer and she can get all the new stuff she sees on TV. Older people don't understand tech, but they still understand commercial that are marketed to them. People who are techies want to the features market to the lock face to unlock. It's crazy to market features to people and not give them the features for 8 months.
Very non technical users freak out if they switch something on one day and it's all different.
It's probably the 18-20 demographic who cares about having the latest versions.
