Intel officially announced the Intel Ultra Mobile platform 2007 (codenamed "McCaslin") for Mobile Internet Devices (MIDs) and Ultra-Mobile PCs (UMPCs) at the Intel Developer Conference In China.

The already announced HTC Shift will be actually based on the new Intel UMPC platform.

Other UMPCs based on the new Intel platform will be available over the summer from Aigo, Asus, Fujitsu, Haier, HTC and Samsung. The new ultra mobile computers will all run on Windows Vista and the Origami interface.
The Intel Ultra Mobile platform 2007 is based on the Intel processor A100 and A110, the Intel 945GU Express Chipset and the Intel ICH7U I/O Controller Hub, where the power and package have been optimized for unique ultra-mobile requirements.

Intel accelerates the UMPC roadmap and announces that the company will release the next-generation platform for MIDs and UMPCs – codenamed "Menlow" – early 2008 instead of late 2008.

Menlow will include a new processor, codenamed "Silverthorne", based on a new 45nm Hi-k low power microarchitecture. The platform also includes the next-generation chipset, codenamed "Poulsbo," providing a single-chip solution. Silverthorne and Poulsbo were both designed from the ground up for MID and UMPC platforms.
At the IDF Intel showed the first Menlow prototype. See a photo of it below (via Watch Impress (Japanese)).

What that means is of course that at the CES 2008 we will see again a new generation of UMPC devices based on this new Menlow platform.
