PCLinuxOS has been around since 2003. It started off as a set of RPM packages to improve Mandrake (now Mandriva) Linux. Eventually it grew and changed and became a standalone distro in it’s own right.
PCLinuxOS uses APT-RPM as it’s package management system. Basically, it uses APT and Synaptic, but on RPM packages instead of DEB. It’s used a variety of desktop environments in it’s time, but currently (version 2011.09), KDE is the only desktop environment available officially.

Once the livecd has booted, you’re asked to choose a keyboard language. For the first time in a while of testing, the screen resolution on my test machine didn’t automatically set it correctly to 1366×768, I had to do it manually. Not a massive deal, though.
