Traditional tablet PCs

           A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device, and running a modified desktop OS designed to be operated and owned by an individual.The term was made popular as a concept presented by Microsoft in 2000and 2001 but tablet PCs now refer to any tablet-sized personal computer regardless of the (desktop) operating system.
Tablet personal computers are mainly based on the x86 IBM-PC architecture and are fully functional personal computers employing a slightly modified personal computer OS (such as Windows or Ubuntu Linux) supporting their touch-screen, instead of a traditional display, mouse and keyboard. A typical tablet personal computer needs to be stylus driven, because operating the typical desktop based OS requires a high precision to select GUI widgets, such as a the close window button.

History of tablet computers

             The History tablet computer and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots.
Electrical devices with data input and output on a flat information display have existed as early as 1888.Throughout the 20th century many devices with these characteristics have been ideated and created whether as blueprints, prototypes or commercial products, with the Dynabook concept in 1968 being a spiritual precursor of tablets and laptops. In addition to many academic and research systems, there were several companies with commercial products in the 1980s.

             During the 2000s Microsoft attempted to define with the Microsoft Tablet PC the tablet personal computer product conceptas a mobile computer for field work in business, though their devices failed to achieve widespread usage mainly due to price and usability problems that made them unsuitable outside of their limited intended purpose.

             In April 2010 Apple Inc. released the iPad, a tablet computer with an emphasis on media consumption. The shift in purpose, together with increased usability, battery life, simplicity, lower weight and cost, and overall quality with respect to previous tablets, was perceived as defining a new class of consumer device and shaped the commercial market for tablets in the following year.

As a result, two distinctly different types of tablet computing devices exist as of 2011, the Tablet PC and the Post-PC tablet, whose operating systems are of different origin.

The Apple iPad

A tablet computer, or a tablet, is a mobile computer, larger than a mobile phone or personal digital assistant, integrated into a flat touch screen and primarily operated by touching the screen rather than using a physical keyboard. It often uses an onscreen virtual keyboard, a passive stylus pen, or a digital pen.
The term may also apply to a variety of form factors that differ in position of the screen with respect to a keyboard. The standard form is called slate, which does not have an integrated keyboard but may be connected to one with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include two touch screens, and can be used as a notebook by displaying a virtual keyboard in one of them.
Early examples of the information tablet concept originated in the 19th and 20th centuries mainly as prototypes and concept ideas; prominently, Alan Kay's Dynabook. First commercial portable electronic devices based on the concept appeared at the end of the 20th century. During the 2000s Microsoft attempted a relatively unsuccessful product line with Microsoft Tablet PC, which carved a niche market at hospitals and outdoor businesses. In 2010 Apple released the iPad based on the technology developed in parallel with their previous iPhone, and reached worldwide commercial success.
