Thats like starting with I have a perfectly serviceable rotary dial landline phone; just what is this bloody smartphone thing supposed to be good for?

Nope. I can easily answer that question. But I’m baffled with regard to a device with a 1 square screen that can tickle your wrist that requires an iPhone to work. Baffled is an understatement.
But, of course, I never did like wearing a watch.
This is probably a better device (Samsung) and it's cheaper... but it isn't "Apple" so it isn't "cool" ,, like you I see no purpose to what amounts to a bluetooth device on your wrist when headsets have been available for decades. Call me when it is a standalone device and doesn't have to piggyback on an iPhone... it's JUST A TOY and will live it's life (after the first month) in the bottom of a jewelry box.
