well it quite a disappointment that BFL units haven't shipped. I have heard if you want to cancel your order they only give you the dollar value back not the coins you paid to get the unit. Isn't that kind of ripping a person off if I paid 30 BTC I should get 30 BTC back, but I guess it was based of the USD price to begin with so its a little fair.
Until BTC stabilizes for a month or so, buying things in BitCoin can drive a person mad. However, if you're mining them when they were in early stages then you got a deal and also did a pay it fwd to the BTC market. As for BFL, I put in a day or so ago for a 30Gh/s single. I look at it as something I'm investing in as well as BTC. My order # is ridiculous, but it seems as though if they are building a robotic assembly line and many frustrated miner's are dipping out then it could pan out. BFL order # of 15,000 are going for ridiculous money, like 1-2k so there is a demand for people who are patient. Just like all things only time will tell. Hopefully just like BTC there will be griping and hindsight ; )
