On my home laptop I run Debian old-stable[1] as the newer SW in Debian stable was memory usage wise too bloated for it.
[1] Note: its PCMCIA network card broke before Lenny became stable, so I don't worry about remote exploits and as I don't have any valuable data on it, I've pasted the password on its cover. I use it fairly rarely, mainly to do some C/Python coding & TeX writing when not at home. If somebody steals it, they are going to be responsible for recycling it. :-)
