Most anyone using Ubuntu Linux has to install Adobe Flash, Java, DVD playback, and other plug-ins to actually enjoy it. Super Ubuntu packs all that essential in from the get-go. It's basically just a re-compiled version of the official Ubuntu distribution, but with a whole bunch of features included that save you the time of grabbing them yourself. File-sharing apps, multimedia codecs, Windows compatibility tools (including WINE and support for PortableApps installations), and lots updates that haven't hit the official repositories are included, but you'll still get official security and application updates through Ubuntu. The creators seem pretty intent on keeping Super Ubuntu up to date, and offer a constantly-seeded ISO torrent and live USB creation tools for anyone looking to try it out. Super Ubuntu is a free download for most any computer running on x86-based processors. It appears to be a 32-bit-only affair at this point.
