Tux Machines (TM)-specific
To be honest, I have used quite a few KDE distros in last couple of years but never saw a resource efficient distro like Mageia 2. Under similar conditions, Mageia performed better than almost all the KDE distros I have used. Plus, with Mandriva Linux going commercial and PCLinuxOS becoming independent of Mandriva, Mageia and ROSA are perhaps the limited ways to know what's brewing in the Mandriva camp. Incidentally both the Mandriva derivatives present really beautiful KDE distros!
With such a background and rich legacy, it is not surprising that Mageia enjoys a huge fan following in the Linux world. For me, the release of Mageia 3 was one of the most anticipated releases of the first half in 2013, after Debian Wheezy and Ubuntu Raring Ringtail. The release announcement of Mageia 3 promises of absolutely the very latest version of Linux kernel and applications, another reason for me to test Mageia's to ascertain it's stability.
