downloaded them all, tried them all and was particularly impressed with VectorLinux, speedwise, but i think I will stick with xubuntu as i can use the .deb files from other systems i have for updates, which saves me hours of downloads. i have tried dsl too but that is a little bit too light and not so easy to use for my girlfriend. I think on a P133 it will be fine but this is still a P4 1.3Ghz. I liked VectorLinux as it flew and looked good at the same time but i am not so familiar with slackware. Not a good excuse, i know, will get back to it later.
Happy 2008 all! and thanks!
