Yi Technologies [2] and companies like Yi are going to DOMINATE the non-smartphone camera market in short order. Just wait for MWC this year...

DJI is pretty expensive and chinese too. In the end it's about the tech to price ratio.
Have you watched the people that use Action cams? Drones, Dirtbikes, Mountain Bikes, Kayaking and more... A warranty doesn't generally cover "Smashed into building buttress at high rate of speed whilst attached my 250mm racing drone, will you please replace under warranty?"
It seems that most people have settled for smartphones for the bulk of their photographic needs. When you can get a similarly spec'd action cam or MFT cam for 1/2 or even 1/3 the price, a LOT of people will jump on that. Especially people that have broken a GoPro... Ask me how I know that :)
DJI has a lot of competition just getting started... The quadcopter world is absolutely on fire and moving amazingly fast.
This probably affects less than 10% of action camera users (who uses action cameras in low light?!). I've only used a gopro either outside (hiking, skiing) or underwater snorkeling. If I can get a similar one for half the price I will on my next purchase.
> For YI's first attempt at a Micro Four Thirds mirrorless camera they got a lot of things right, but there's still room for improvement.
Let me draw your attention to... "First attempt." It will get better and most likely less expensive.
