Not quite true. Many of us bought it for situations described by the poster I quote below. I bought it so I could drop my phone in my jersey pocket while on a bike ride, and track my progress, any incoming calls, emails and texts while riding, without having to stop and pull out the phone. But it didn't quite measure up, as I state in my response below...
I, too bought a Pebble on Kickstarter for some of the same reasons you mention. Specifically to use while riding my bike (Think 40 miles at 18 miles per hour, not a ride in the park). But, aside from delivering the product way, way later than originally promised, they were way too slow getting the SDK out, and the device was far too buggy for far too long after it's introduction. Consequently, to this day there still isn't integration with my fitness app of choice, and the most popular fitness app in the App Store, MapMyxxx. And when I tried to use it with the bicycling version of runkeeper it was so buggy that every time I received a text or notification from another app it would crater the Pebble, and I couldn't track my ride from the watch anymore. For me, it's basically been a dumb sports watch that cost $115, and needs to be charged at least once a week. What makes me sad about all of this is that I really had high hopes for it when I opted in.
Having said that, I will step back and take another look tomorrow, when I go on a hike. I admit that I haven't even tried to use it for a couple of months now, and I know they've issued a couple of updates. But my first, second, third and fourth impressions of the device have been meh, at best.
