I'm not a watch person, and the only reason I occasionally wear one is because it's a Garmin and I'm recording an outdoor activity with it. But while cycling, when the phone in my backpack makes a notification noise, it is kind of handy to just be able to look at the watch to see what kind of notification it is - the kind hardly worth looking at or the kind worth stopping and pulling out the phone to reply to. This particular gadget doesn't have a microphone and any app interaction on it involves a multi-button dance. But if there was a single button audio recording app, I can totally see myself using it. Especially as you get older (I'm guessing - can't interview younger me) fleeting thoughts can be awfully fleeting.
