The Ubuntu Mobile and Embedded (UME) project aims to derive an operating system for mobile internet devices using Ubuntu as a base.

UME will extend Ubuntu by providing infrastructure for mobile development, with all of the necessary components integrated into the Ubuntu package archive, ready to install and run, or to tailor for custom mobile applications. It will be a different architecture (lpia), but live in the same archive as the normal Ubuntu packages.

Ubuntu Mobile initially will target "the emerging class of ultra mobile, small handheld devices which are Internet-enabled."
