	Well, I'm sure that someone out there really wants a dual processor pentium
pro because it sounds like it goes to 11...Spinal Tap reference:)  Anyway, in
the commercial world, there is plenty of reason to own a multi-processor
machine, but often that is done to efficiently run applications that take
advantage of multi-processors.  At work, for example we have several Sun 4000e
servers which run applications like Sybase over Sun Solaris 2.6.  Sybase is a
very sophisticated application that allows individual processors to be used
for different things.  This is very handy in enterprise computing.  By the
same token, a great deal of our web stuff is done in perl5, and having 8
processors means that a single webserver can fork off dozens of simultaneous
perl5 processes without grinding the machine to a halt.  It should be noted
that in the Sybase instance, the same application runs on different
processors, whereas each perl5 process is dedicated to one processor in the
second.  In the long run, I don't believe that the PC is the target audience
for most MP applications...But I'm sure there are plenty of NT enthusists out
there just dying to tell me how ready Windows NT is to take on Sun Solaris:)
