In addition, smaller nodes have more heat per area, because energy consumption doesn't fall down as fast as area shrink.

Basically they are fine for mobile, but desktop expect more performance per money. I remember how Intel thought: "Everyone would go to cellphones and tablets, and technology limitations for non-enterprise users would be fine. Enterprise users have enough money to stomach costs of special nodes."
