It of course depends on your usage profile. I have a laptop with 3 Gigs of RAM 
without swap. I don’t do really fancy stuff on them. Noteworthy things: 
Blender, X-Plane (flight sim), Hugin, some small VMs and of course the 
occasional compiling. Mostly, I do only one of those at one time. I even have 
set up a ramdisk in /var/tmp/portage for emerge. Except for kdelibs its 1.5 
Gigs are more than enough. And if the ramdisk is empty, the free space is used 
for RAM.
