We will stipulate that we may have made mistakes in technology development, funding of our manufacturing infrastructure, or choice of how to commercialize our technology - in particular whether to have led with 100G or set sights on future architectures.  Many of those “mistakes” were due to a lack of sufficient funding for an ambitious project, and the need to choose one path over another and the constant need to generate "quick" results whether it be revenue or customers, especially in the public markets.  However, there is no question that we would be in a better position had we been able to introduce products to market a year or two earlier.
