If you go to asics you sacrificing the most valuable thing, and that is adoption. You simply deny 95% of people the ability to participate.
Actually ETN with it's simulated cellphone mining has the best adoption available to be honest.
Just because a handfull switching forth a back miners have a coin less now doesn't mean for sure that adoption will be sacrificed.
Right now on the cell phone 131k simulated miners, that's pretty strog in my opinion.
