Steve Jobs gets credit for inventing the iPad, but the idea goes back to 1987. The vision for this device occurred when Jobs was not a part of the company.
The iPad is the highest selling tablet computer on the market, holding nearly 70 percent of the market. This also translates into Apple holding most of the profits due to tablet sales. It is the first tablet to ever hit the market. Steve Jobs did not design the iPad with his own hands, but he is responsible for the ideas about how the device should perform and how it should look.
