we thought it was cool to dial a number to get the time and temperature, when the neighbor wasn't using the party line?
Husband wears an Apple Watch. Time, temp, health status, calendar appointments are all visible when he turns his wrist. We were recently separated at a baseball game (St. Paul Saints), and it was too loud to use a phone. I texted him, his wrist buzzed (he wouldn't have heard his phone ring), and he saw my message on his watch. He tapped "OK" and we found each other.
Pretty darn cool.
