2 GB for my home machine and 4 GB for my work machine. The few applications 
that use most memory are Kontact and Amarok. Amarok uses +1GB. Kontact uses 
about 700 MB. (One day, I will switch to mutt...).

I'm only running a small number of applications. If everything is ok with the 
software, these are the only solutions. I'll probably buy some memory. It's 
pretty cheap these days.
