I'm generally an openSUSE/PCBSD/Bodhi guy, but I just wiped the computer clean last week and thought I'd take the opportunity to install something new, for fun. I installed Mageia 2, not realizing it was about to be replaced.
Conclusion: good distro! It installed cleanly/easily, had a good-looking KDE4 desktop with sensible defaults, and was intuitive and easy to use. The DVD came with a lot of software on it, but once I initialized the repositories I was able to find every package i need except one.
To the haters out there asking 'what's the point' I'd say it's a distro that's kind of a sure thing if you give it to a friend to install. They've done sensible, methodical, professional work and it shows. It's avoided going insane like Ubuntu, has tools that make configuration pretty straight forward, and was easy to use. "But it's no different than any other distro!" I'd say these days there's not a huge amount of software being written for Linux so increasingly all the distros are starting to look the same. It's not that different from Ubuntu but Ubuntu is not really that different from Fedora or openSUSE or Crunchbang or whatever.
They're also building a pretty good quality, constructive and helpful community - that counts a lot. Their forums are useful and full of helpful people, all there for a reason.
Good distro, would install again. A+
