Sorry if I wasn't clear - I meant closed-source applications. Mandriva will package up many of the commonly used closed-source applications that are free (as in free beer or free lunch) and only put those packages in the powerpack versions. They do this to add value to the powerpacks because it makes it a lot easier and simpler to get all this stuff when its packaged in RPMs for your distro, and especially because it can install nvidia, java, acrobat reader etc. by default on the install.
Anyway if you download the free version all you have to do is go to the websites for these closed-source packages and download and install them, like you'd have to if you were running Windows.
I mean that this powerpack dont really consist a real commercial-pay-to-get software e.g staroffice or crossoveroffice
No they sometimes include trial versions for pay-to-get software like this but AFAIK they've never included the full version of anything you'd have to pay for.
In conclusion you can download the free version from their website, install it and then setup your access to the repositories (at http://easyurpmi.zarb.org
) and get all the open source software that comes with the powerpack version, plus a bit more. You will then have to download closed-source things like Nvidia Java, Flash, Adobe Reader etc. from their respective web sites and install them if you want them.
