Subject: Flash:Today, Mandriva introduces Mandriva One, a CD live and install, based on Mandriva Linux 2006.
Mandriva One, the first Live and Install Linux CD!
An operating system is generally available in a Live or Install CD, but not both on the same disc. Mandriva One differs in offering an all-in-one CD, based on Mandriva Linux 2006. It is a great way for all users to save space and time. This high qualityLinux distribution does not only include Live and Install functionality, but also a selection of the best free softwares available.
Rubbish ! Mepis has had this functionality for years 
These guys should get out from under their rocks a bit more often. See http://www.mepis.org if you want a first class distro on one CD. There are numerous Debian distributions that have this functionality and have done for a long time, not too mention the Gentoo live CD which now includes a graphical (albeit complicated) installer on the live CD.
