If we ignore the Apple keyboard for a moment, with DIY mechanical keyboards, you can customize travel length, travel resistance, and click. Getting the force and travel length correct, for me at least, mean I spend significantly less energy typing. My fingers and lower arms are tired if I'm using a regular keyboard for an hour. Perhaps the optimum is not either extreme. Not an Apple like keyboard with almost zero travel, and not a keyboard from the 5$ bin, but something in between. And it's not the same for everyone.
