I do not understand why everyone is fixated on the initial 100 Mh/s estimate. It is an estimate of the initial hashrate per share and will grow just as Asicminer's does/has albeit probably not at the same rate. When I first looked into Asicminer everyone was screaming about how only an idiot would buy into something that gets you around 56 Mh/s per share (if my memory serves me correctly). I'm sure glad I was one of those idiots.
