Ubuntu is preparing to launch a special version of its operating system for use in embedded and mobile devices. 

The forthcoming Ubuntu Mobile and Embedded Edition, due in October, will be tailored for Intel's 2008 Mobile Internet Device (MID) platform. The first devices are expected to ship in 2008.

Ubuntu is a popular desktop Linux distribution. The software also offers a server version.

Intel unveiled the MID platform at the Intel Developer Conference in April, announcing a partnership with Chinese Linux vendor Red Flag which is developing a special 'MIDinux' version of the operating system.

The chipmaker has repeatedly touted Linux as its platform of choice for mobile devices at the expense of Microsoft.

Intel chief executive Paul Otellini criticised Microsoft in May for failing to develop a feature rich, energy efficient operating system for mobile devices.  

Intel envisions the MID as a device with a 4in to 6in display with an instant-on capability that offers a simplified user interface. It will target consumers and so-called 'prosumers'.

MID devices will be consumer appliances more than fully-fledged PCs, with different models focusing on specific use cases.

One design will focus on connectivity with video conferencing and VoIP capabilities, for instance, while another will be more entertainment centric offering video, television and gaming features.

Yet another could act more like an information and location device that combines GPS navigation with access to information on local stores and news.

Although the MID will use the same low-power processor as the Ultra Mobile PC (UMPC), it is priced more cheaply. The UMPC runs Windows and targets the professional and prosumer segments.
