Engadget: Think for a second, what major consumer electronics company doesn't have a tablet to show? Right, Sony. In fact, the rumor womb has been conspicuously barren of salacious Sony tablet tattle ever since Apple's iPad was announced back in 2010. Oh sure, Sony's owned-up to the development of prototypes that fill a "very important position" somewhere in between its own Vaio PC lineup and the Xperia Play byproduct of its Ericsson commingling. But beyond that: zilch, nada... until today.
