unless, of course, when the answer to the question "does the
current hardware run the software needed" is "it does, but one
component, the RAM, is the rate-limiting factor".  Or, some
other easily upgraded component, like the CPU, the drive, or
the network card is the rate-limiting factor.  256MB is $40,
if you only have 128MB and Mathematica needs 192MB to do its job
without paging excessively, then upgrading to a new $1000 machine
with 128MB would be a very expensive mistake.
