RAM is still about 100x more expensive than HD. So I always recommend
you use about 2% of the money you spent on RAM to pay for the HD space
to handle swap.

Actually the deal is: either use enough swap (about 2x RAM) or use
none at all. 

A "good" operating system will want to use say half your memory for
buffers, even if there are processes using that half of your RAM. Not
when they are actively using it, but only after they have NOT used it
for say an hour. Then the users of the machine will see efficient use
of the resources. It does have the disadvantage that when you come back 
in the morning, your xterm may have been swapped out because of the
nightly backups and stuff....
