iPad has been four years! See how to change - Computer World (press release)

iPad

first saw the light of day January 27th 2010, exactly four years ago. Steve Jobs showed it to the world at a press conference at the Yerba Buena Center for the Arts in San Francisco. Later it turned out that the design of the Apple tablet existed much earlier, but the company decided that, first, as a test, will launch the first iPhone. It must be remembered that even these 4-5 years ago touch screens were a real novelty for consumers, but about those 10-inch nobody even thought.
