Some of the tech you like is about to get more expensive -- at least for the companies that design them, if not you. True to earlier plans, the Trump administration has formally enacted a new round of tariffs against China-made products that will take effect September 1st. The measures will hit tech companies with 15 percent tariffs on a range of goods, with Apple potentially feeling the pinch harder than most. The hikes will affect AirPods, the Apple Watch, some Beats earphones, the HomePod and iMacs.
