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:

 

  • Screen size: 5-7 inches.
  • Screen resolution: minimum 800 × 480 resolution.
  • Weight: less than 2 pounds.
  • Display orientation: landscape or portrait.
  • Input methods: Touch screen or stylus.
  • Optional: add on Bluetooth or USB based keyboard .
  • Operating system: Windows Vista Home Premium, Windows Vista Enterprise, Windows Vista Business, or Windows Vista Ultimate.
  • Network connectivity: Wi-Fi, Bluetooth, Ethernet, 3G and EVDO.
  • Battery life: 2.5 hours or more.
  • Processor: Intel Celeron M, Intel Pentium M, or VIA C7-M.
  • 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 subnotebook, ultraportable, mini-laptop, MID or mini-notebook.
