Gear Review: Pebble Time Round

A few days after I started wearing the Time Round, Pebble's ultra-thin new smartwatch, I shut off notifications. This was partly practical---I get too many notifications, and the iPhone offers no filtering control over them---but also a thought experiment. Right now most people see a smartwatch as nothing more than a notification machine, a slightly faster way to see what that buzz in my pocket was all about. What if we took that away? What else could it be?
