To me, it's interesting how Apple's Touch Bar on the keyboard often gets criticism from technically oriented people, yet in theory it appears to solve the needs of everybody here: just figure out a way to program your desired key into one of the spaces and you have anything you need. I've never bought one of those machines, so I have to ask, what was the problem with it? Was the issue just not having tactile feedback? In pictures, it appears nice looking at least.
