"Everything we do tends to be highly dependent on technology progress and I think now for the first time we believe that we have the technology not in a research stage but in a stage where we can provide tangible parts to customers to test that is a prerequisite to having a pipeline of revenue going forward."

The above quoted from FJ's post.  

What I'd like to hear, is "we have now placed parts to customers who are in the process of testing same."  The wording they use is such that you might assume they have, but is far, far from definitive.  What I wrote, on the other hand, is not difficult to write, thus, I assume the placement/testing has not yet begun.  Until it does, there lingers the possibility that it won't, and that's what many here, including me, fear.  Once it does, then the concern switches to, "how did we do, did they like the products, and are they ready to order them?"  At that point, much risk is removed (compared to the risk we now have).
