Ubuntu Netbook Remix is optimised to run on a new category of affordable Internet-centric devices called netbooks. It includes a new consumer-friendly interface that allows users to quickly and easily get on-line and use their favourite applications. This interface is optimised for a retail sales environment.
Canonical has collaborated with Intel and is working with a number of OEM’s to deliver Ubuntu on netbooks in retail. In keeping with the philosophy of our best work being available to everyone, the core remix product is available to all through the Canonical repositories. This version is free to download and modify by any user.
