  As far as my desktop system, a black-box tool is exactly what I want.
Whether I'm designing hardware, writing firmware, testing either,
gathering data, controlling instrumentation, or typing an email, I want
(and demand) a tool that works 100% of the time, the way I want it to,
and doesn't get in my way.  That's what I have, right now, with a
high-end PeeCee running Linux.

  A Linux fanboy I am not, and you know full well how much I dislike
PeeCees.  But that doesn't change the statement above.

  I'm reasonably adept at figuring out what a UNIX system is up to, as
you well know.

  I think we have a disconnect.  Please re-read what I said above your

  Ahh ok.  I, on the other hand, want to make phone calls and send text
messages.  That's why I have a phone.

  Understood.  To each his own.  I don't like some of the design
decisions either, but there exists nothing better in the current era,
that I've been able to find.  If I'm wrong (and I'd love to be, since I
hate running friggin' PeeCees) please point me in the right direction.
