I never meant to imply they didn’t, but I never really used them because they weren’t very discoverable. With the Touch Bar I can tell just by looking at the “keys” what they do, whereas with fn-keys all I see is F1, F2, Fn... none of those tell me anything.
I can find out, sure, but my experience tells me I won’t, so for me the Touch bar is a win, simply from a discoverability standpoint.
