That it depends on the OS, and that there is no rule :-)

I've seen Linux boxen run very well as workstations with *no* swap at 
all, and small amounts of RAM (256 or 512).

I'm also seeing at work Windows 2000 peecees that are crawling on their 
knees because they have 3 times as much swap as memory. Instead of 
saying "I need memory!", they just get horribly slow and unusable (and 
since there is no message, no need for the IT department to add memory, 
of course).

On Solaris 9 x86, I used to have only 256 MiB and 650 MiB swap, and KDE 
was really annoying klauncher was crashing usually after a few minutes.
I added 256 more, no change in swap, and no more problem.

Just my own experience - I know other people have different ones :-)
And I'm planning to fill up my MB with 3 GiB, to be ready when KDE 3.2 
is out ;-)
