PCLinuxOS Review: What Does PCLinuxOS Have to Offer? (Linux.com)
PCLinuxOS has one of the strangest takes on package management I've run into on Linux. PCLinuxOS is based on Mandriva, so it uses RPMs. I will admit that I've always been a fan of RPM and Yum for managing packages. What I've never been much of a fan of is PackageKit. PackageKit is a graphical front-end used to handle RPM and Yum, as well as Debian packages when used on those distributions. PackageKit has always (in my opinion) been inferior to the likes of Synaptic. And that is where PCLinuxOS shines. The developers of this rpm-based distribution have taken the Synaptic front end (usually associated with apt and apt-get) and added it as the package manager for PCLinuxOS."
