I was going to order the $650 yesterday.
Seriously.
But not having any shipped and reading about their power consumption issues is what held me back.
I think I'm more upset they raised the price than I didn't preorder.
Use the $650 to buy bitcoins and in 6 months when BFL starts shipping, you'll look at the value of your bitcoins and be so glad you didn't waste your money on a pre-order now.
