People that have worn the Watch say that they take their phones out of their pockets far, far less than they used to. A simple tap to reply or glance on the wrist or dictation is a massively different interaction model than pulling out an iPhone, unlocking it and being pulled into its merciless vortex of attention suck.
One user told me that they nearly “stopped” using their phone during the day; they used to have it out and now they don’t, period. That’s insane when you think about how much the blue glow of smartphone screens has dominated our social interactions over the past decade.
This is exactly what I've experienced since getting my Pebble smartwatch last year. It's helped me greatly in getting me to stop fiddling with my phone when I'm out with friends while still allowing me to stay on top of urgent notifications, usually from my boss.
It really doesn't seem like much, but the time you save by not having to whip out your smartphone every time you get a notification really starts to add up. Being able to stay on top of your notifications with a half-second glance has done wonders for allowing me to live more in the moment instead of behind my iPhone.
This time and attention-saving solution is definitely not the most sexiest feature to market, but it's something that everyone will benefit from once they actually experience it.
