I was thinking on future generations of Apple watch. With the iPhone we've seen better cameras, larger screens, Touch ID, Siri, and internal upgrades. But..what can you do with a watch? I'm sure it will become thinner and they'll release new bands. But it doesn't have a camera, and relies on the phone. Also you can only make the screen so big. So what kind of upgrades (other than software) do you envision? I'll hang up and listen.
