Definitely makes way more sense for a macro pad--you don't hit those keys very frequently so switches are less significant but the key's effect changes often so the screen is useful. Tactility is good, I never liked Apple's Touch Bar for that reason, you had to look to be sure what you were doing. Can't imagine those switches being preferable for the primary keys, but would love to see something like this in the old IBM AT F or XT layout: 10 function keys in two columns on the left side where they could easily be combined with meta keys. Back when I had those (mid to late 1980s) I relied heavily on them, but I almost never use function keys since they moved to the top of the keyboard (and are effectively out of reach).
