Your point on the politeness of the Pebble is exactly why I'm wearing one right now. I hadn't worn a watch in years, and when I got a Pebble for a project, I thought I would use it just long enough to write some code for it. But I love being able to fend off and deal quietly with the various intrusions of my digital life. I can fend off a phone call, see a text, or be reminded of an appointment without a fit of beepilepsy. It makes my life more serene even when I'm alone, but what really sells me on it is when I'm around others.
