The next version of Sony’s tiny VAIO C1 notebook will be powered by one of Transmeta’s power-saving Crusoe processors.

The sub-notebook will hit the shelves in time for the Christmas season, launching simultaneously in the UK, Japan, and the US.

Sony’s decision to house the processor is a minor coup for the fledgling chip maker, which claims the inclusion of Crusoe should boost battery life by around 50%.

Sony is the first manufacturer to make a firm commitment to Transmeta’s processor range.

Although manufacturers such as IBM have demonstrated laptops using the chips at trade shows, no specific product launches have so far been announced.
