A few weeks back Todd Landstad was a guest on my podcast. Tomorrow you can hear more from Todd on how to build great UMPC applications on Windows Vista.
I can recommend attending this if you are in a timezone where the time is acceptable - hint hint...

Here is the offical blurb:
An ultra-mobile PC (UMPC) is a fully functional computer that is small, mobile, and runs a complete version of a Windows operating system (currently Windows XP Tablet PC Edition 2005 and soon Windows Vista). UMPCs present many new and exciting opportunities for application development. Although your existing knowledge and skills transfer directly to the UMPC, there are some unique circumstances to consider when you are developing applications for these devices. Join us to find out what is involved in developing for the UMPC, and learn how to create outstanding applications for these new devices.
