Why won't BFL publish power usage for their units?

I know, for my part, I would not want a device that runs at 200w at 60 GH/s - it would never see a positive ROI.

USD/BTC was much lower in October. The price has gone up significantly since then, which makes that comment invalid. In fact, the price is almost 10x what it was when he said that. Srsly, do some math before you try trolling next time.

How about we do the math on the difficulty change?

2012/10/17 = 1,468,218
2013/08/06 = 37,392,766

Difficulty has gone up 25x. That means that device is even less profitable now than when he made that comment. Although Josh was trying to trash a competitor, this is the one rare example where he turned out to be right. BFL is so late that their devices will never ROI.

May never ROI. Since difficulty can fall (or stop rising), there are infinite scenarios under which a BFL Single could generate ROI.
However, the more BTC rises in USD, the better off the early pre-order people would have been just buying BTC from Gox or BTC-E instead of BFL.

Oh, and nice head shot about the difficulty math. Grin
