Skydiver with 3 GoPros in the family. I started with the 1, got my wife a 2, and then I upgraded to a 3. The V1 is still alive and kicking, but the image quality was so much better on the 3 that I felt like I had to upgrade.
Also, we see new jumpers every year, and the first thing they want to do is start jumping with a GoPro (even if we don't want them to for safety reasons).
I think they're doing a good enough job with new features that people like me will keep upgrading for a while.
Dropped one without the case: lens onto concrete floor and it chipped it.
Consequence of fumbling while trying to take it out of the case for SD card retrieval and charging. Now, I unmount the case, take it to a desk in a carpeted room & open the case.
I found mine washed up on a beach in a waterproof case (had no way of identifying the true owner). No idea how long it had been floating in the ocean before it washed up on the beach, but it works perfectly.
