What does any of that have to do with Apple requiring people to have an iPhone to use their watch? Maybe you don't want an iPhone and are satisfied with the functionality of the watch alone. Maybe you have one of the zillions of Android phones out there and don't want an iPhone for that reason. Literally no other smart watch that I know of requires that you have a phone of any kind, so I just don't see any reason for Apple to require it with their watch.
