Here is what we know: 1) Steve Jobs was focused on developing an Apple TV set when he passed away, and told biographer Walter Isaacson that the current TV interface is broken and that he had figured out a solution. 2) Apple has put together prototype TV sets. 3) Apple has been negotiating with content providers. And here's what we don't know: 1) Whether Apple will actually come out with a TV set. 2) When it would come out with one.
