Comment Teensy 3.0 shipped on time (Score 4, Interesting) 100
My own Kickstarter project, used to launch Teensy 3.0 (a low-cost Arduino compatible board with a 32 bit ARM chip), shipped on time.
We had 2 levels of rewards shipping, half within 2 weeks, the other half the next month. We did end up shipping the last several September rewards on October 1st, so technically we slipped 1 day for small group of rewards. Otherwise, all the September rewards actually shipped in September, and the rest shipped before the end of October.
Of course, a tiny number of backers didn't respond with their address or had other logistical problems with their info. Most of those shipped late, but even then, we resolved nearly all of them in October.
