On 27 January 2010, Steve Jobs, the now deceased boss of Apple, the first iPad to the assembled audience to see. It was called a tablet computer. There already existed like tablet computers called PDA (Personal Digital Assistant) or palmtop. But these were intended for use in business and had limited options and a few programs.
The iPad was something new: a hand-portable computer for the ordinary consumer. And by the presence of an operating system iOS, the number of functions are not limited to keeping a diary and word processing as a PDA. Just like on a PC or laptop was running all kinds of programs (called apps) possible. From word processing to playing games, taking pictures to Facebook tracking.
precisely this flexibility, combined with the ease of use of the iPad, the device to one of the greatest successes of the past three years. So influential that there are now hundreds of brands and types of tablets from other manufacturers on the market. The iPad is still one of the most popular tablets. Though it is only because the device is working properly and there are so many different apps available.

The mother of all tablets consists, like its descendants, largely from a touch screen: a screen that allows you to operate the computer by touch. This allows for a mouse and a keyboard unnecessary. The rest of the computer behind the screen, with the edges in contact with different connections for other devices and a few buttons to control playback.
Since the introduction of the first iPad that no number-had come in relatively short time various types of iPads appeared. Due to the rather inconsistent naming them by manufacturer Apple, there is often confusion about what the iPad can and even whether that still officially on sale. Apple gave two models later taken off the market. Not because they were not working well but to compete with newly released models to avoid. This ‘disappeared’ models are often still from the remaining lot or on eBay.
