"Mandriva Linux Free is the version without any proprietary
software or drivers. It’s for those who are truly committed
to “free” software at its most…well…free.
Mandriva Linux One is a free download that also contains some
proprietary drivers and software. The Mandriva Powerpack is a
version that you must pay for and it includes all of the stuff on
the free versions as well as additional value-added software. You
can get the Powerpack via a one time payment or a subscription.
"You can also buy Mandriva in a portable, flash version too. I
downloaded Mandriva Linux One 2009 for this review. I’ve
never been an ideologue as far as “free” software goes
and the Powerpack is far more than I’d need if I were going
to use Mandriva as my main desktop operating system."
