I'm now using this Gutsy based distro on my main Linux PC, well worth a look. From their website;
Linux Mint is one of the surprise packages of the past year. Originally launched as a variant of Ubuntu with integrated media codecs, it has now developed into one of the most user-friendly distributions on the market - complete with a custom desktop and menus, several unique configuration tools, a web-based package installation interface, and a number of different editions. Perhaps most importantly, this is one project where the developers and users are in constant interaction, resulting in dramatic, user-driven improvements with every new release. DistroWatch has spoken to the founder and lead developer of Linux Mint, Clement Lefebvre, about the history of the distribution.
