http://www.dreamlinux.com.br/english/index.htmlAnother Linux distribution.
Combines the best of different worlds.
Multimedia works great, uses the Xfce desktop manager (which will suit slow PCs well), easy installation and re-distribution, etc.
It's based on Debian and Mepis, two of the most popular Linux distributions out in the world.
One of the best things is Mkdistro, which allows you to build your own flavour of Linux.
Looks pretty much like Mac OS... so if you are used to Mac or like Mac, you might want to give it a try.
