PCLinuxOS is fairly easy to set up, offers good performance and includes a wide range of software. I generally enjoyed using the Plasma 5.8 desktop and the System Settings panel makes it easy to customize the Plasma environment. I very much enjoyed working with the Control Centre as it makes tasks like setting up network shares or working with the firewall easy. In short, there is a lot about PCLinuxOS that I enjoyed.
However, I did run into several minor problems. Nothing show stopping, but a handful of "papercut" style issues that bothered me. For example, PCLinuxOS makes it easy to install VirtualBox, but not to get working VirtualBox guest modules. When running the live environment on my desktop computer I had trouble with sound and network time synchronization. A few programs were missing their documentation files and I ran into an error while setting up secure shell access. None of these items are big issues in themselves, but when combined they suggest to me that not enough people are testing the distribution and reporting issues to the developers.
In general though what stood out about PCLinuxOS was the distribution provides a rolling release platform that receives regular updates, while also providing a relatively conservative environment. Most distributions either stick with a static, point release system or offer a rolling release with cutting edge packages. PCLinuxOS seems to be finding a pleasant middle ground where core components and the layout of the desktop are conservative while the desktop applications are the latest and greatest. I like the balance that is achieved between providing a traditional environment and newer applications.
