Definition from Wikipedia - tablet:
A tablet computer, commonly shortened to tablet, is a mobile computer with a touchscreen display, circuitry, and battery in a single device. Tablets come equipped with sensors, including cameras, a microphone, and an accelerometer, and the touchscreen display uses the recognition of finger or stylus gestures replacing the usage of the mouse and keyboard. They usually feature on-screen, pop-up virtual keyboards for typing. Tablets may have physical buttons for basic features such as speaker volume and power, and ports for network communications and battery charging. Tablets are typically larger than smartphones or personal digital assistants with screens 7 inches (18 cm) or larger, measured diagonally.1234
Tablets can be classified according to the presence and physical appearance of keyboards. Slates and booklets do not have a physical keyboard and typically feature text input performed through the use of a virtual keyboard projected on a touchscreen-enabled display. Hybrids, convertibles and 2-in-1s do have physical keyboards (although concealable or detachable), yet they typically also make use of virtual keyboards.
The format was conceptualized in the mid-20th century5 and prototyped and developed in the last two decades of that century. In April 2010,6 the iPad was released, which was the first mass-market tablet with finger-friendly multi-touch and a dedicated operating system. Tablets experienced a rapid rise in popularity and ubiquity and became a large product category.7
As of November 2015, tablet use in the world is led by the iPad with a market share of 65.66% and Android tablets with a market share of 32.08%.8 The iPad holds majority use in North America, Western Europe, Japan, Australia, and most of the Americas. Android tablets are more popular in most of Asia (China and Russia an exception), Africa and Eastern Europe.

As portable computers became closer to the modern laptop, they became widely used for a variety of purposes.
