Well, of course it costs you megs, but nowadays you can get a price of
about $1/1€ per gig for a desktop hard drive.
I haven't tried using swap files, but that's because I have room to
spare in all my hard drives except this laptop, but I'm gonna fix that
in a few days.
IMHO, it's better to have a few extra megs of swap than a few apps
killed for lack of memory.
