Virtual memory is never a usefull solution -- it's only a temporary, slightly-
inconvenient solution to not having enough RAM. If you only have 8 megs and
need to run something larger _just_once_ it's great: no having to buy more
memory, just use the hard disk. If you need that much memory on a regular basis,
tho', you'll quickly find that it's much too slow. Also, it _does_ cost you that
disk space. (How many optical drives do you have hooked up to give you that
Gig, anyway? :-))
