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.
