Ace, you should see my sound system. I may have a large flatscreen tv, but the sound system is a 70's deck system with an 8Track and two huge speakers I salvaged from a movie theater. It looks tacky as hell, but kinda cool in a retro way. That and I can turn it up loud enough so that if I wanted, I could mow my lawn and listen to pandora at the same time.
As to what industry is going to be hit first, I think the stores like Party City will feel it first. Most of their cheap toys for party favors come from overseas. So birthday parties will be more expensive, then we move to a lot of the aftermarket parts for sound systems that the younger kids like to tinker with. Then we move on to the electronics like tablets, laptops and game systems.
