There's an old joke about NASA developing a pen that works in outer space, while the crude, clueless Russians used pencils.
I've been rocking the Fisher Space Pen since 5th grade!
If they shipped in October you will have massive competition and difficulty. Hashfast promise on October 20th and theirs is only $14 per gh/s 28nm technology compares to $17.50 from KNC. Bitfury 56nm is guarantee also going to be out in October. That will be a great Oktoberfest.
Hashing power from HF is going to be enormous, with the purchase from their IPO plus the purchase from their customers.
So pray that Knc can deliver in Early September or we will all be fried and roasted. Better still hit your Refund and get it done with.
Thank you for making that ignore click a much simpler choice and feel free to continue lowering the Gross Domestic IQ.
