A step backward in design; not forward. Think: thinner, worse in most-every-way keyboard design.90 % of us have cases on our phones. Even the official Apple ones have issues with the volume controls and having to press harder etc. so tactile really will only be for the naked users out there.. the rest of us will suffer…
So if they are tactile I recon we will all end up adjusting our muscle memory to swipe down from the top to adjust volume. Or watch as we ask Siri to turn up the volume and the lights turn off.
