What is a UMPC? Ultra-mobile PC (UMPC) is a hand-held computing device capable of running a Windows operating system. A UMPC is larger than a personal digital assistant (PDA) but smaller than a laptop. Microsoft and Intel created a design specification for the UMPC in a project called Origami. According to Microsoft, although the exact specifications may vary by manufacturer, the baseline specifications for an ultra-mobile PC are as follows: (1) Screen size: 5-7 inches. (2) Screen resolution: minimum 800 × 480 resolution. (3) Weight: less than 2 pounds. (4) Display orientation: landscape or portrait. (5) Input methods: Touch screen or stylus. (6) Optional: add on Bluetooth or USB based keyboard. (7) Operating system: Windows Vista Home Premium, Windows Vista Enterprise, Windows Vista Business, or Windows Vista Ultimate. (8) Network connectivity: Wi-Fi, Bluetooth, Ethernet, 3G and EVDO. (9) Battery life: 2.5 hours or more. (10) Processor: Intel Celeron M, Intel Pentium M, or VIA C7-M. (11) Storage: 30 gigabyte hard disk drive or larger. Because design specifications often overlap for hand-held computing devices, a UMPC might also be referred to in marketing literature by a variety of names including sub notebook, ultraportable, mini-laptop, MID or mini-notebook
