In the Solaris books, and other posts I have read I have seen a lot of
Sun engineers compare kernels heralding the benefits of sunOS. I just
racked it up to a slight bias, after all they were sun employees, kind of
like hearing Linus talk about the linux kernel. Then when I seen
fishworks and some of the material that it was capable of I was very
impressed.  I guess what sold me was the fact that they could tell from
I/O probes and graphs that a network interface card had malfunctioned.

So I appreciate posts from real people doing real things that tell it as
it is.
