I don't see why people are complaining about the price. Seems right in line to me. Maybe a pinch cheaper, like 5.9 btc, but it's perfectly reasonable. You get everything, plug and play, at 1Th/s. Ease of use is worth a little more in my opinion. Only draw back ... They aren't shipping tomorrow. They are shipping in a week or two.
bitmain is known to ship early, but even then, I will have received at least 3TH/s of S1's....for alot less although 2x the heat/energy.
If I had the money, I would be buying up S1's right now, too. Then I would likely be selling them to the come lately's on ebay in May.
