True, but...
...on my development box, I discovered the hard way that not having any swap was leading to significant slow-downs during my work day...Especially once I added VMWare into the mix (almost 300MB for that sucker right there.)
So I added a swap file (not a partition, since I built this system long ago.)
Things are still slow when I run out of RAM (1GB currently, with plans to upgrade to 2GB), but not nearly as bad as they used to be.
Swap space has allowed me to not have to spend money immediately on RAM for the price of a single 2GB file on my / partition.
