John Gruber on the new iPhones and the new Home button:
The home button on both iPhones 7 no longer physically clicks. Instead, it’s a force touch sensor, and it uses the improved Taptic Engine to provide simulated click feedback. Alas, it’s nothing at all like the new Force Touch trackpads, which use haptic feedback to simulate an artificial click. With the trackpads, the feedback feels like an actual clicking trackpad. In my opinion it’s uncanny. I like the simulated clicking on the Force Touch trackpads more than the actual clicking on older trackpads, primarily because it feels the same everywhere on the trackpad, whereas the old trackpads were less clicky the closer you got to the hinge at the top of the trackpad.
This will take some getting used to.
The new home buttons don’t feel like actual button clicks at all. It feels like the iPhone is clicking, not the button. This was especially disconcerting at first. In the hands-on area at the event last week, when everyone was experiencing it for the first time, reaction was overwhelmingly negative. Five days later, I’m getting used to it. But I don’t think I’ll ever like it as much as the actual clicking Touch ID home button on the iPhones 5S through 6S.
We’ll get used to it. My BlackBerry’s had physical keyboards. Who uses those anymore?
