I have been using Mandriva on past 4 or 5 years as my Main stable Business OS and though I have been trying some other Linux Distros just for trials. But I have to say that Mandriva never let me down and it really deserves to sit in the best Business and personal desktop linux. Top notch features of mandriva among other distros..
1.faster and quick system response
2.really ergonomic fonts
3.legendary mandriva control centre
4.great theme and artwork
5.simplicity but powerful underneath.
This distro surely better than Ubuntu..No questions...
