“It” is finally here. Apple CEO Steve Jobs unveiled the iPad tablet device at the Yerba Buena Center for the Arts in San Francisco to a packed house amidst thunderous applause Wednesday. After months of speculation, which reached a fevered pitch over the last two weeks, it was absolutely imperative that Apple’s iPad live up to the hype. And it does. Jobs characterized the iPad as a third device category between a notebook and a smartphone; and given the features and the form factor, that is a credible claim.
