I'm not too sure these "small-scale" miners are gonna cut it come the next halving. It would seem to me they are only gonna collect dust which will later be really expensive to spend. Maybe I'm missing something. On the other hand I liked that they're offering educational materials, but I'm not totally on board with the "open source almost everything" philosophy. We'll see I guess.
I think the intention was not to sell a "mining computer" but rather spreading the technology to the more tech savy crowd as a gadget to play with and to develop. I think they
missed a opportunity to create a device, which will enable mass mining. You could create a computer with loads of ASIC upgrade options. Entry level to hardcore miner...
A single device, with no upgrade options will always fail, as difficulty increase. A computer with the ability to ROI will be a attractive option.
.... Some early miners bought
expensive GPU's and after using it for mining, they sold it to gamers and made some profits from the GPU's and the mined coins combined.
