Ubuntu

Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. This special version of Ubuntu has long term support, which means it will get free security updates until April 2011 on the desktop and April 2013 on the server. There is no extra fee for the LTS version, we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.
