I first bought RedHat Linux OS 6.0 for use on a Thinkpad i1412. As a first time Noob, this didn't go well.
Next was Sun's JDS, which installed, but, sound wouldn't enable. A common problem in the early 80's, but, it allowed me to experience Linux, learn some basic Bash commands and realize that I needed to learn more so I could rid myself of Windows.
Mandrake 9.2 came next, then PCLinuxOS, then Mepis 6.5. I've become a fully functioning Linux user at that point and started erasing Windows off of my boxes.
Started with sidux and learned a great deal, I used it for a couple of years. Onset of KDE 4.0 made me look for a Gnome2 based distro, and I found Fedora, which I've been using ever since. Except the Gnome3 horror show had me switch back to KDE. By this time KDE 4.5 was very much as stable as the old KDE 3.
As I used Fedora, my old friends (the sane ones) from sidux forked aptosid and started "siduction". I became a user and a contributor to siduction.
So, now half my machine run Fedora, the other half run siduction, and, I'm a happy Linux camper.
