Great article although it does miss out a few small distro's, vector springs to mind. Although that is a Slackware derivitive, maybe not everyone's cup of tea.
Im going to try and boot DSL on my parents old old pc from 1997 I think it was, it has been running as a firewall but this seems a good reason to have a play with it. Has anyone else given DSL a try? It seems to be a decent distro that you can add items to if you have the space.
