An ultra-mobile personal computer (UMPC) is a Microsoft term that refers to a handheld device capable of running Microsoft’s Tablet PC operating system (OS). Original design specifications for UMPC were created by Microsoft and Intel. The UMPC’s specifications were quietly launched in February 2006 and code named the Origami Project. The device is larger than a personal digital assistant (PDA) and smaller than a laptop and uses a touch screen or stylus.
