It's easy to use a Pebble while driving. Not like you can't take one hand off the wheel briefly to hit a button.

Can't you just say "Hey siri, add a note"? I add reminders, send texts, etc. that way.

Yeah, there's lots of places you can't speak out loud bc it's disruptive to others though. Personally I set a lot of Siri reminders, but it's weird and uncomfortable to talk loudly at your phone in public spaces so I can only use it at home or outdoors. If the ring can follow through on the promise of being able to whisper to it, that's fairly valuable imo

You can whisper to Siri on your phone or your watch too - that’s not a ring exclusive.

Definitely, but Siri is terrible at understanding quiet speech and you have to hold your phone/watch right up to your mouth. A ring is definitely a much nicer form factor for that.

There is the small matter of a 3-4dB price difference between this ring gadget and your "Hey Siri" capable watch.
