Just to chime in. I punted a few quid towards Pebble when they were on Kickstarter and, in return for my faith in them, I got a a ‘Kickstarter Edition’ watch.
At the time, I wasn’t entirely convinced that it would take off with the general public, or even with myself. But, a year and a bit on, I’ve worn it pretty much ever day. The fact it doesn’t look ‘flash’ or ‘cool’, means it makes a great incognito daily watch, like the Casio FW91 was (and is resurging). The fact I can control my music from it is not just a gimmick, it means I don’t have to constantly rummage in my pockets for my phone to change the track. There’s a nav app that means I can use the sat nav in the car and get directions on the steering wheel - actually much less distracting than a TomTom (other brands available).
What’s best with Pebble, is that there is an awesome SDK, which allows anyone who knows a bit of C to write apps for it. Also, the 7 day battery life is much less annoying that you’d think; especially given that it charges in an hour or 2.
