If the mainframers were the ones footing the bills, then the cost
might enter into their reasoning.  As it is, they tend to focus on
the technical aspects.

Still, the costs are eroding the market for mainframes. (Depends on
whom you ask.)  Interestingly enough, it isn't the hardware costs
that are the biggest problem; it's the software.  Software is
generally charged for by the MSU.  The vendor (IBM or other vendor)
charges you based on the total load that the processors handled for
that period.  The more work you got out of the machine, the more
you have to pay for the software.  The assumption is that you used
the software more, and therefore got more value out of it and
required more support.  (We're not just talking about the OS here.
This is common for justa about *any* mainframe software.)

I have discussed this a little on the mainframe mailing list.  Some
of them think it's unethical and greedy (as I do).  The rest of
them feel it's a fair way to do business, and it gives a "break" to
the smaller businesses.  Of course those that support it generally
work for one of the ISVs (Indie Software Vendor).

I hadn't realized until recently that HP was producing a direct
competitor to the IBM z9 called Superdome.  I guess it's been
around for about 2 or 3 years.  A big Korean corporation just
bought two of them to replace 7000 mips worth of IBM mainframes.
If that trend continues, maybe we'll see some of the big iron come
down in price.  Maybe.
