"What's the compelling use case for a smart watch then?"
The problem with this question is that what it's REALLY asking is "What's the compelling use case for a smart watch FOR ME then?", which is unanswerable for anyone but you. I am reminded of this every time El Reg puts up a story about phone or tablet sales. The "I just want a telephone with $RidiculouslyLongBatteryLife," or "Tablets are toys with no compelling use case," brigades come out and proceed to ignore or actively dismiss EVERYONE who points out that, FOR THEM, $Function or feature is indispensable or has, at the least, simplified their life in some way.
It's perfectly fine to say "I see no compelling use case in $Gadget for ME," but another thing altogether to generalizie to "There is no use case for $Gadget." One is intellectual honesty and one... isn't.
