I have 4 airport expresses and use the remote app on my iPhone to control my desktop iTunes . And then cast to as many airports as I want . Works awesome . <| sep |> Yes , I ' m hoping a lot of his campaign promises turn out to be typical politician BS , but it seems he will certainly reverse some of the environmental policies of the previous administration . The main two issues I am concerned about are 1 his promise to slap 45 % tariffs on goods from China and Japan with 35 % tariffs on goods from Mexico and 2 his promise to round up 13 million undocumented immigrants who live in the US . I ' m hoping that the threat of tariff wars was pure lies and posturing to negotiate new deals from a better starting position . I imagine what he really wants is simply a win to be able to negotiate some China trade deal that appears at least superficially better than previous deals . With respect to rounding up undocumented immigrants by the millions , I don ' t think it would be an easy task , and I know many of us would engage in civil disobedience to prevent this from happening to the extent we can . If he were to follow through with either of these two promises it could have a devastating negative impact on our economy , and the entire world economy .
