Microsoft Corp. on Thursday unveiled its ‘Origami’ project, a paperback-book sized portable computer, which is a hybrid between a laptop PC and a host of mobile devices that the world’s biggest software maker hopes will create an entirely new market.

The Ultra-Mobile PC is a new kind of computer. It combines the power of Windows XP with mobile-ready technologies that make it easy to access and use your software on the go. With small, lightweight, carry-everywhere hardware designs, you can connect and communicate, accomplish any task anywhere and at any time, and be entertained and informed wherever life takes you.

Lighter than two pounds (0.972 kilograms) with a seven-inch (17.78-centimetre) touch-screen, the new “ultra-mobile” PCs (UMPCs) use microprocessors from Intel Corp. and run a modified version of Microsoft’s Windows XP Tablet PC edition.
