TBQH I'll be the first in line. I've been wearing a Nano v.6 watch (LunaTik) for two years, it's super limited, and it's relatively ugly. But it's saved my ass (as a preschool teacher) a few times when my Nano v.7 has unexpectedly run out of battery.
If Apple makes something that can interface with my iPhone, it will change my whole life. :)
Or just a watch-sized nano with Bluetooth FFS.
