* Too many remote controls. One for TV, one for AppleTv, one for PS5 if I want to see a movie on bluray, one for the Denon AMP, etc... There should be a standard for that. Something with a touchscreen and an API manufacturers should support. * Touchscreens in cars (already mentioned). My Toyota is not even capacitive and it's a car from 2017. More generally... Touchscreens where they're not needed, like ATMs or vending machines: with all this covid fear, they're not hygienic. * Wireless headphones: battery, quality of sound... I fear the day there will be no wired headphones available on consumer market. I don't care about high quality wireless headphones, I don't want to charge my headphones * Messaging apps. I have to keep iMessage, Telegram, Whatsapp & Signal on my phone because I have different contacts using different apps. It was easier in the SMS era
