while we are on the topic, what about chips from AsicMiner? They should be testing the first batch and we'll probably know real specs and price in a few days, but the theoretical specs were about 0.3 J/Ghash and 0.5-1$/Ghash, which seems pretty competitive to me... of course this is for the chips only, full boards would cost more per Ghash

Generally speaking I must agree that I remain skeptical with the preorder economy: why should you effectively loan bitcoins with 0 interest and without any certainties on what you'll be getting and when?

Having said that, I must also agree that I know nothing about mining and OgNasty obviously knows a thing or two
