I have had a Pebble watch for about 16 months. It syncs with my iPhone and announces who is calling me, and gives me the source and the first line of all my emails. As a physician who gets dozens of emails every day, I find this extremely handy, because I can see it when I am doing other tasks without taking out my phone. It is handy in public, as I can know who is calling even when the phone is on silent, and can be paged in a moment without disturbing anyone. If I set my phone down and walk away, the wrist still alerts me if I am within about 50 feet of the phone. And a glance is all I really need to differentiate the trivial from the serious. In social circumstances, there is the danger that one’s companions may remark “are you bored” or “do you need to be somewhere else”, but generally the topic immediately turns to the Pebble watch. The Apple Watch should expand this experience to many more people and have many more uses.
