They will first go "I don't buy those damn consoles and gamer PCs every few years", then find out once their new iPhones will be much more expensive...
Everything will be more expensive, if it uses a modern CPU. Phones, tablets, computers of any type from any company (both Intel and AMD are fabbing consumer CPUs on TSMC, as is Apple and Qualcomm), TVs, set top boxes, everything.
Right now TSMC is basically the only fab anything consumer-facing is made on, which is not a great thing in general, but vice president trump just decided that anything electronic needs a hefty price hike.
