Last week at Computex Taipei the Canonical OEM team had unveiled Netbook Remix. Netbook Remix is based upon the stock package selection found in Ubuntu but with specific optimizations for Mobile Internet Devices and Ultra Mobile PCs. These optimizations include user-interface improvements for potentially new Linux users as well as making the desktop easier to work when running off a small screen.
Netbook Remix also has optimizations lower on the Linux stack for power efficiency and performance when using Intel Atom hardware. If you are unfamiliar with this next-generation class of mobile devices, check out our photos of Intel Menlow UMPCs from CES 2008 this past January.
Canonical's Netbook Remix won't be appearing on mobile devices until later this year -- and these software changes are still very much under development -- but interested parties can already check out the source-code and Debian packages for this work.
