It is useful. Theoretical physicists use Form
(http://www.nikhef.nl/~form/). Its unique feature is the ability to
manipulate (relatively) efficiently expressions whose size is, say, 100
times larger than the available RAM (disk sorting algorithms are used to
collect similar terms). Many important calculations in theoretical high
energy physics could never have been done without Form.
Of course, lisp-based systems are different: if maxima begins to swap, it
will never complete the calculation. But at least with 64-bits we can
utilize the whole RAM.
