Hi,
I started with Mandrake 10 in 2004, tried Debian testing, then Ubuntu one year and a half then chose Archlinux at early 2006.
In 2008 tried PCLinuxOS light Minime, and kept on dual-booting since. I am now a PCLinuxOS contributor and Archlinux.fr moderator.
I had also tried : Pardus, Slackware, Slax, Foresight, Toutoulinux, Slitaz, and a few more.
I tried once a fork from Sun Opensolaris, and that has been fun ! But this is not the subject here, right ?
