I have not received my watch yet but should by next Monday. The biggest reason for me buying S4 is the fall Detection feature. I am 44 however this feature will benefit me in a tremendous way. I broke my back while serving and the damage is pretty extensive. I walk either with a cane or walker. I have severe nerve damage which causes me to fall several times a week. My wife works and I am home alone. I have fallen and knocked myself out a few times over the last couple of years. To be able to send an alert to her and family is a game changer for us.
I am also upgrading from a S0 so there is the benefit of it being faster too.
