A Tablet PC is a laptop or slate-shaped mobile computer, equipped with a touchscreen or graphics tablet/screen hybrid to operate the computer with a stylus or digital pen, or a fingertip, instead of a keyboard or mouse. This form factor offers a more mobile way to interact with a computer. Tablet PCs are often used where normal notebooks are impractical or unwieldy, or do not provide the needed functionality.There are many operating systems in use on devices marketed as tablets. Note that most tablet PC software is targeted particularly for the Microsoft Tablet PC API, and will not run on devices without Windows Vista or Windows XP Tablet PC Edition. Care should be taken when researching a tablet system or any device or software that claims to be designed for tablet PCs, as the phrase does not guarantee compatibility.
