For all the consumer technology on show at CES, the elephant not in the room was Apple, bearing the burden of expectation that the company will somehow transform the smart television category in the same way that it revolutionised the smartphone market.

Or will the ultimate television screen simply be a large, slim, ultra-high-definition display that we address with other devices? I would welcome your views.
