VIA's rolling into the sub-notebook market with a different tack: open-sourcing the platform. If you're looking to design your own sub-notebook, you can grab the CAD files for VIA's reference platform under the ShareAlike license. I'm wondering about what else besides sub-notebooks we might see as a result of this.

"The OpenBook is based on Via's 1.6 GHz C7-M processor and VX800 chipset. The design includes an 8.9-inch screen with a resolution of 1,024 pixels by 600 pixels and calls for a hard disk with a capacity of 80G bytes or more."
