I like the idea of building a simple brick-powered introductory miner with USB connection. Something a n00b can buy, inexpensive but reasonably efficient and not requiring advanced computer knowledge or miscellaneous hardware stashes to use and maintain. Just saying, Dogie's not the only one thinking it. I've always said there wasn't enough (or good-enough) hardware in the mid-range consumer sector between USB stick miners and farm-grade hardware.
the problem therein lies that mid range miners, like USB stick miners are pretty much novelty items now. Sales volume won't command the demand on build investments, and making power bricks is just more manufacturing expense.
I do believe however, that there is no requirement to build humongous large-power miners with such efficient chips. FC would do better to keep product under 4TH/s... even that is a good home mining rig at these efficiencies and which can also be deployed in a farm setting.
I guess we'll have to wait and see.
