Will Tom's post on his own forum convince you?

For the record, I'm not a BFL supporter. My interest is in seeing those who've pre-ordered ASICs get the most accurate information possible about when they can expect delivery. I think Tom has done pretty well at this to date but that people are understandably frustrated when significant delays are only announced at the 11th hour, no matter which company is announcing a delay. I think many people would rather have a company say "February" and deliver on time or early than have them give a date and keep pushing it back.
