Worth mentioning that mining will follow Moore's law, and therefore at some point we won't see exponential growth that we've seen in the last few years. So, while new products might temporarily set them apart compared to the competition, the margins get lesser as time goes on, until eventually affordable options are out there for everyone.

At the moment, we're at the point where mining is relatively priced out for those without quite substantial investments. That should change in time though as above.
