Sorry for the late reply.

I have to assume that they put these on YouTube as a general info source/marketing tool, and also something they can point potential customers to towards providing a uniform, understandable, more detailed message as to the merits and capabilities of their systems.

And I really liked their identification of current/past customers, along with "Experience=Credibility". Prospective customers could conceiveably contact current/past customers for input as to performance of the systems, and of PDSG. Along these lines, consider this: if their experience reveals anything but success and positive business relationships with those customers, would they be so forthcoming?

JMHOs,
