recently a friend of main sent me great story – s-f full of humor. it's called 'toilet flush in linux'. it's a future vision, what would happen if linux-guys would rule the world. this is funn, but you can see from it how good it is to have a choice – monopoly will never be the best solution.
read full toilet flush under linux text (in humour part). sorry folks, but this there is just a polish version.
