On purpose?
The biggest problem with the product is the battery life is utter crap, particularly in extreme weather conditions. In the cold, on a full charge, it will last about 30 minutes. Overall, it is a truly amazing product and they have made it possible for the average Joe to document his adventures without spending thousands of dollars on hiring a professional photographer/videographer.
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.
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 do the same on my bike, not a gopro but a Sony AS15 though.
