Update
We are getting ready for the arrival of our assembled blades. The development of USB-stick miners is actively on the way and heading to its sample batch. The series of the auction will last for several rounds and include the USB-stick miners in later rounds when they are out.
I think a nice 'incentive' that could also help bring attention to investing in ASICMINER would be to offer the USB stick miners to share holders only (if possible) or offer a hefty 'early bird' discount to share holders.

"'incentive' that could also help bring attention to investing in ASICMINER" is certainly not friedcat's concern. why? because bitfountain is not selling any shares and wont be for the foreseeable future.
Anyway, there should be NO special treatment of shareholders. There is no overall profit maximizing effect in favoring shareholders. If you want to buy, buy like everyone else.
