the funny thing about all of this: there's no one absolute for keyboard design; it's all invention. there's no right or wrong... it's not as if the 11th commandment was "let there be a computer keyboard with fat, clicky keys".
so apple does what it does, and we adapt (or not). then we get used to the current keyboard, and, some time later, there's a whole new design.
and so on. personally, i like change, and have no complaints about the current keyboard (or my 2016 12" macbook, where i do most of my actual typing).
