When someone has a 'session' with a wearable that involves anything more than the the most minimal of operations [1], I feel like that's the "stylus moment" [2]. Sure, there are narrow use cases when 'interacting' with a wearable is conceivable where a phone still is not (e.g. while biking or jogging). But that's going to run into the same problems that Glass runs into: how many people can really justify an electronics purchase to enable interactive computing during those situations?
