I became a big fan of PCLinuxOS since February this year. First time, I used PCLinux (I am still a Linux n00b) when I downloaded the Feb'12 release and installed it in one of the systems I have. I am not a KDE fan but PCLinuxOS is different! I have used Ubuntu mostly in last 2 year or so and I could never successfully update Ubuntu - I had to do fresh install every time! PCLinuxOS is actually the first Linux OS which I could upgrade without breaking anything. Also, there's a knowledgeable and helpful forum in place to help you out of issues like screen not displaying proper resolution and stuff like that!
The appearance hasn't changed significantly from the last edition with minor facelifts here and there. Overall, there's no drastic change to shock the users. Linux kernel is updated to 220.127.116.11bfs and KDE is 4.8.3. I guess you can install KDE 4.8.5 or 4.9 (final version to be released) in PCLinuxOS as well. NVIDIA and ATI support is out-of-the-box and it works well with common graphic cards.
