I own both of those, actually! Big fan of Logitech going quite literally back to their C7 serial port mouse from 1985. I don’t use the MX Keys with my Mac anymore, because it doesn’t have TouchID, but I do use the MX Master mouse.
I’d still like the ability to manage Apple input devices from the iPad! Like, we got the ability to format drives from the iPad and that was a nice step towards “real computer” status.
I mean, alternately Apple could put a sync button on their devices. But I don’t think we’re getting that.
