PCLinuxOS (PCLOS) for short is one of the few popular distributions out there that uses Mandriva as its base while others are based on some sort of variant of Debian. PCLOS uses KDE 4.6.5 as its desktop environment and is available for both 32bit and 64 bit systems. As with a lot of distributions, PCLOS comes as an installable Live environment so you can try it before you commit to installing it on your system.
Installation of PCLOS was somewhat quick and there were only a few options to really choose from. Where users might get stumped is under the Security setting; it asks for a password and it is for the bootloader and not your administrator password which will be asked later on. Other then that, there were no qualms with installation process.
