Wrist better than pocket
"When you get down to it, lifting your wrist to your face is not much more convenient than reaching into a pocket."
This is palpably not true. Glancing at your wrist is significantly less disruptive to what you're doing than fishing a phone from your pocket. As a Pebble user for the last 18 months, I've come to massively value the 'on wrist' notifications of texts, emails and calls.
