We all know Apple Watch will have the Speakerphone option. Now Apple has positioned it in a way where it's an "I'll call you back" and hang up type of use case scenario. Now, that being said lots will abuse it, and you will hear two way conversations in the store in public about things that should really be discussed in private, and so on and so forth. Remember those old Nextel walkie talkie phones? Oh god. I hope people will still pull out their iPhone to talk and not bring back speakerphone culture.
