Linux OS which one ???

Debian Lenny FTW

Ubuntu or mint. Mint I believe has a roll-back feature built in, and it supports multimedia files out of the box i think.

numero uno !!!

Ubuntu FTW !!

Ubuntu is the easiest through my own experience. Try that.

I recommend archlinux , it's easy once you read the wiki and very fast . Also it's optimized for i686 architecture whereas most of the other distros are not . Give it a shot

Start with ubuntu because it has an awesome community, then be special.

Mint :yup:
