I disagree, and since none of us can (or could) see the future either way, it's really not relevant. If btc had stayed at $100, MANY less people would be mining, difficulty would not be anywhere near where it is today, and your machine would have easily produced those bitcoins. It is all connected.
You are right, it comes down to making a gamble, some of us won, some of us lost. And as Matthewh3 noted, the HF gamble went bad for everyone involved. I just want to inject a bit of reality into this thread where people are screaming EVERYONE made out by buying their October batch. Note that I am happy with the hardware, I think it's a fantastic piece of art.
In any case, I will run the unit into the ground trying to recoup my investment, I should be able to get close in the next 6 months.
I actually passed on the Neptune, with no set delivery date, many other manufacturers shipping soon, and the mysterious unknown miner adding hashing power every day, I felt uncomfortable making another gamble.
