The FAQ page at Origamiproject site has been updated.
Here are some of the most important questions that have been answered:
Will UMPCs be compatible with Vista?
UMPCs that meet the Vista hardware requirements will be compatible with the new operating system. We are beginning to test the new UMPC devices with the Beta versions of Vista to identify any compatibility issues.
What software is compatible with the UMPC?
In general, if a program runs on Windows XP, it will run on the UMPC as long as the device meets the program's minimum hardware requirements. The smaller screen size and resolution may cause some clipping on programs, but the units support increasing the resolution, which in most cases will solve the problem. Some manufacturers may include hardware buttons to give you quick access to different resolutions. Standard resolutions include, but are not limited to, 800x480, 800x600, and 1024x600.
Can I play Halo on this device?
Lots of folks saw the Digital Kitchen video that showed someone playing Halo on what looked like a UMPC. The video, which was intended for viewing by Microsoft employees only, showed our ultimate goal of running all Windows software on this ultra-mobile form factor. However, in this first release, youll probably be primarily limited to casual games.
