The UMPC is first and foremost a computer. It runs a full version of Windows XP and Vista operating systems software. It might come equipped with full versions of popular Microsoft software applications such as Office, which includes Word, Excel, PowerPoint, and Outlook
The UMPC is not a sit-on-your-desk computer, nor is it even a sit-on-your-lap computer; rather, it is a hold-in-your-hands computer. It is so small and lightweight that you can hold it in your hands, much like you would hold a book. It also sports a touch screen, making it super-easy to do tasks both simple and complex.
Another helpful piece of functionality is GPS technology. Whether you use the Microsoft version or software from another provider, you can use the UMPC to give you directions from place to place, tracking your progress on the computer in your hand as you go. Such navigation can take place via satellite, 3G devices or Wi-Fi protocols.
