Here is a theory that people will soon realize is true:

If you can order a mining device immediately (i.e. not pre-order) you will never make ROI on it.

If companies already had these devices and they were profitable, they'd mine with them, not sell them. If they sell them, they will charge so much that they won't be profitable. If they charged so little such that they were profitable, everyone would buy them and difficulty would rise so that they quickly became unprofitable.

They have demonstrated working examples of all the devices weeks ago. BFL stated they had all of the parts needed to clear the backlog.
But BFL has stopped shipping (or at least nobody is getting devices and BFL is not claiming to have shipped any).
The only reason would have stopped by now is a lack of parts. I see no other plausible reason to not ship. *
What plausible reason could there be for a lack of parts at this late a date? Did they run out of chips?
Does everyone have to wait the 100 days it takes BFL to get a new chip order in?

Come on everyone. Quit whining already ! DUH! It's completely our fault they can't get their own house in order.
