Oh god, not the Apple marketing buzzwords again. this is not an "innovation" this is something that has been tried/discussed for years and found that it does not work too well. it is an oversight at a very fundamental physics level to which the solution is not to have the antenna exposed i.e. like every other antenna. if the solution to an innovation is to go back to what others have tried already and because you too failed, that is far from innovative. it's the exact opposite, it's a naive step backwards then back to using what everybody had done before.
