In the given form factor, what sensors could be added, without dropping existing ones?
I guess, one way would be to introduce special categories of watches, such as medical ones, that drop gps and others for oxygen / ECG or new sensors.

That said, blood glucose seems like the next big win. Rumors have been that they're working on it.
There are bloodless sensors now and in development.
What you recommend based on measurements or people acting on that information can have asterisks on asterisks, but still needs to hit a minimum threshold for usefulness.
