I did find some of Jeff's notes a bit disconcerting though.
If that box works for 1 month with periodic restarts and then fries itself into a ball of molten plastic, Jeff will still have seen a very nice ROI that is hard to find anywhere else. He made almost 15BTC in less than a day, it's probably paid for itself already by now...
That may be true, but my concerns aren't with just his unit. My thought was that his unit would sort of foretell the problems with other units. Jeff and a number of others may be able to make quite the ROI, but there's a chance that there are a number of others who could receive a product that doesn't meet the standards currently set.
Why do you think that? I would guess it's the other way around; this is the unit that was put together in a panicked last minute rush with whatever parts were closest at hand in order to get it out the door. Future versions might be the ones with newer and better tested software, fans that all match, the right cord, the wifi antenna included, etc, etc.
I see your point, and it does make sense. The way I thought about it was sort of the opposite; ship out the best working product they had on hand so it could be reviewed...fully complete or not. The object would be to make the best impression before the start of the "no refunds" batch #2.
