I think that is a great distro, very easy to use and with some nice tools. They seems to have now more stable versions than before, so...
I use the MCNLive based on Mandriva for my usb and also have Mandriva installed on a desktop. It is an excellent choice, its been around along time and is a very mature system - one of my favourites.
Its initial release was a little buggy but i think they have ironed most of them out. I can't really fault the OS except that it hasn't worked too well on my particular systems and i don't have the motivation to try and work out the problems.
KDE 4 needs work and polish, they are too busy trying to emulate Vista and Mac OS eye candy, there are some issues but otherwise Mandriva is an excellent distro, one of the only ones where my Canon printer worked right out of the box. Excdllent hardware support.
Hello, its a nice distro. i found some issues with it as well. KDE4 isnt very stable. 4.1 is better but still not ideal. i like KDE4 alot but im waiting until its more stable. KDE4.2 does look nice indeed! only in beta atm. 4.2 is for refining and bug fixing.
