Neither the rasberry Pi hardware... why not simply release a marketplace which allows decentralized micropayments that eventually hit the blockchain?
It only makes sense if we assume that the mining chip allows people to get bitcoin without the hassle of buying it and their objective is to grow and strengthen the bitcoin ecosystem by decentralizing mining and increasing node count. Remember alot of these investors are bitcoin bagholders too and are probably concerned about the centralization of mining and node drop off...
That's the point.
The device as it stand is a pilot, eventually the mining chips will be embedded right into your computer's motherboard.
