the problem is the price of this device ... you can build an atom motherboard+RAM+SSD and 12v 10A supply for less and buy an U3 after this (on the same supply).
And you could make U3 run on rpi with no difficulty and little to no technical knowledge. Also I don't think the purpose of this machine is to get revenue from mining as much as utilizing smart contracts. So the average cryptocurrency user would have actually nothing to do with it. The hashing power of that machine is so low, that it won't likely roi on itself. But we never know, now do we. I'm not the target audience for this product so I think I'll skip this one for now. Maybe future.
