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.
