Since all the distributions I have tried PClinuxOS has always been the simplest in everything, so I decided PClinuxOS would become my first Linux distribution. PClinuxOS has worked on all the hardware I have tried.
FEATURES
PClinuxOS comes in different editions featuring differen Window Managers and different Desktop Environment, the DE used by PClinuxOS are: KDE, GNOME, XFCE, LXDE, Enlightment, Zen Desktop.
The system requirements of this system mostly depend on the Window Manager, but require less resources than Windows 7. This Distribution should work on every modern PC that is not older than 5-6 years. http://blog.redmondxp.com/
