You get texts/emails on watch so you can glance at your watch and read it without pulling out your phone.

You don’t listen through your watch but use it as a more convenient interface to change a song/playlist.

The test use case is while you are driving because you can talk to it and it will type out what you’re saying well. Rather than pulling out your phone and trying to text back.

It also monitors vitals and steps. It is also handy when I forget my phone in the car and I need to text or make a quick call.

I could go on but I’m done typing.
