Project Origami defines a specification for computers with a 20 cm (8-inch) or smaller touch sensitive screen at a minimum resolution of 800 × 480. To make it more suited for the small form factor, Windows XP Tablet PC Edition is used with slight tweaks to the interface. In addition, a software suite known as the Touch Pack Interface is included to make the interface more suitable for use of a stylus as well as hands. When the UMPC was disclosed at CeBIT 2006, Samsung, ASUS, and Founder had near-complete devices on display.

UMPCs have enough processing power to support audio, video, and gaming, in addition to having rich support for browsing the internet as well as for other communication and networking applications. Windows Media Player is included, with a special skin designed to provide a better experience on the small screen. The devices also feature DirectX 9–class graphics, and all applications available for standard Tablet PCs are expected to be compatible.
Prices of UMPCs are gradually coming down to the US$500 range. Battery life is expected to increase from the initial 2½ hours to 8 hours. Most UMPCs are now available with Windows Vista although many new UMPCs come with the option to have XP or Linux installed, as some devices are too sluggish to run Vista. One example of this is the Samsung Q1 Ultra which originally launched with only Vista versions, but has subsequently launched Windows XP versions. This is largely due to the fact that current UMPC hardware is usually too close to the minimum Vista requirements to be comfortably used.
