The big question on many people’s minds is the keyboards: Do they resolve the reliability issues that have surfaced ever since Apple switched to butterfly mechanisms? All Apple is saying is that the new keyboards were engineered to be quieter. But I think only time will tell whether the keyboards were also engineered to be more reliable. Maybe, as Apple says, the only problem they sought to solve was the noise. But, if they also sought to improve the reliability of the keyboards — to fix the problem where keys get stuck, among other problems — I think they would only admit to fixing the noise problem. Marketing-wise, I don’t think they would admit to a reliability problem in the existing butterfly keyboards (especially since they’re still selling second-generation keyboards in all non-TouchBar models), and legal-wise (given the fact that they’re facing multiple lawsuits regarding keyboard reliability) I don’t think they should admit to it. So whether they’ve attempted to address reliability problems along with the noise or not, I think they’d say the exact same thing today: only that they’ve made the keyboards quieter. I have no inside dope on this (yet?), but to me the reason for optimism is that they’re calling these keyboards “third-generation”, not just a quieter version of the second-generation butterfly-switch keyboards.
