though i'd love to wear a smartwatch, my primary concern is battery life. having to plug it into a charger every other night would be a huge dealbreaker. it would have to use sort of inductive charging (still not optimal since you need a mat everywhere you go). Mechanical watches for decades have used hand winding, kinetic self winding, solar recharging technologies, but would these be sufficient to charge a full -on electronic device? doubtful.

once they solve the battery issue, the idea will be a HUUUGE cash cow.
