Definitely not an OS for professionals, very buggy, but it does have all plug-ins and such for Internet.
very plug and play, but not good enough for a main OS.
-My Opinion

PCLinuxOS is a great easy to use distro that has 7 different options for desktop enviroments, plus several of those are available in a minimalist format, ready to be customized to fit your needs. I use the LXDE version on all of my computers (ranging from a Fujitsu P-4 1.4GHz, 512MB RAM, 20GB HD to a dual-core Intel Dell PC). I even run it on an old HP laptop with a P-4 1.3 with 256MB of ram with no speed issues.

I tried the KDE 2009 PCLinuxOS, and I liked it. Cool, easy to use, Mandriva-based, aptitude equipped... there's a lot to like. I went with moonOS over this one because I prefer lighter environments to KDE (even though KDE rocks!), and E17 is a lot of fun.

I noticed the newly released PCLinuxOS has an E17 edition, and I'm looking forward to trying this one out. If it outdoes moonOS (which would be hard to do), then I'll probably make the switch over.

I really liked this distro when I tried it via live USB (http://www.linuxliveusb.com). PCLinusOS is a KDE formatted, easy to use distro with good eye candy and great functionality. Use of the terminal isn't really even required with this distro, which people trying Linux for the first time will appreciate. After all, the average Windows user doesn't really go into the command prompt for much of anything! I am not using this distro currently as I feel there is opportunity to improve on the look and "feel" of the distro. Plus, I prefer lighter-weight distros... As awesome as KDE is, its a bit chunky.
