Re: And exactly what is supposed to power the ring?
"Besides, it might be the size of a wedding band, or it might be more like one of those little ring mice people use for presentations, or it might be complete bunkum."
My money's on complete bunkum.
Just sizing it so that it fits any given mug fanboi consumer is only one part of the problem - another is that the consumer will often be part of a family, so even if it fits the family member who normally hogs the remote, when that person isn't around it's unlikely to fit whoever is second (and so on) in the pecking order.
The other thing mentioned: The 9.7" iTV thing? As the article highlights, that's the same size as the iPad. My money is therefore not on it being a separate device, but an iPad app. That's assuming the Apple TV, as described, is real anyway.
