A stable OS with good support (via forum)requires regular updates (weekly or fortnightly) but is very simple to do.
As PcLinuxOs is continuously updated it is always bang up to-date.
Software not in the repository (it is huge) seems easy to install as rpm.
I have not marked this as excellent as in all OS.s there is always room for improvement but it sure comes the top for me.
I attempt to try most distributions over time, if they crash on first install I consider them as not worth trying again until a new version comes out.
Strangely enough I have as yet to get a straight UBUNTU to work first time! but have many of the derivatives.
My system has 10 hard disks, 2 optical drives two sound cards, dual cpu's (Intel), gforce 9500GT video card, two mice and two keyboards, as well as trust wp8060 tablet.
Works as a server in the background, desktop development in the foreground.
All works well accept sound, fiddly to get working at times.

too dangerous to use (seems to hunt & corrupt other distros on hard drive), not worth the forum abuse. They censor bug reports, ban, wipe posts and harass you on other bug reporting sites.
