Canonical has just released the new version of Ubuntu 12.10, also known as Quantal Quetzal. If you decide to download the new version from Ubuntu’s official webpage, you will notice a rather provocative message. Above the download button, a slogan appears urging the users to install Ubuntu 12.10 instead of Microsoft Windows 8, not because of Ubuntu’s superiority but just to avoid the drama of Metro UI. In a matter of fact, it says ???Avoid the pain of Windows 8. The all-new Ubuntu 12.10 is out now???.
