On this page you can download Microsoft's Origami Experience 2.0.
This makes your UMPC more useful with touchscreen.
Also see my review: Origami Experience 2.0 download and review on VAIO UX
It is compatible with most Windows Vista (and possibly also Windows 7) UMPCs. Windows XP UMPCs are NOT supported.
