Hopefully BFL will get their act together at some point and will actually fulfill all the orders.
I am waiting on confirmations on BFL before I buy anything.
Yeah, I've seen enough to make me think it's not *entirely* vaporware, but they're clearly a company that doesn't have their act together (either have never done hardware manufacturing before, and hence underestimated every step of their supply chain, or deceived customers to get early funding).
That said, I bought a single, mostly because I had some bitcoins in my wallet from a couple of years ago that were suddenly worth a lot more.
I'm hoping ASICMINER comes through at some point, they seem more on the ball.
