Today, Apple announced the new incarnation of their so-called hobby, the Apple TV. The new device is focused on streaming, which is a welcome improvement from Apple’s erstwhile expectation that users manage a library of multi-gigabyte movie files. But the more I think about it, the more I doubt that the iTunes Store that is tied to the Apple TV can continue to thrive. I suspect that without a big change in its business model, it will soon begin to show signs of decline.
