This is why all the belly aching of late is ridiculous.  It's happening before our eyes people, we are now making things that are going into the marketplace, we have the goods.  Now let's watch it all unfold over the next couple of years, it isn't just going to stop and we fold up shop here.  The technological hurdles are behind us, we are now in the adoption phase, with so many exciting opportunities, we only need to hit on a couple to make us all wealthy.  Relax, we're closer than ever as we sit here today, the past is just that, the future is all that matters now.
