I think the idea was interesting, but the execution and adoption, ehhh. It sacrificed buttons for the touch bar, while it could have both. And it's a very expensive feature for very little. I wonder if a touch bar with physical buttons would've worked better.

There's also a Windows laptop out there with the equivalent of a touch bar, but much bigger and iirc it tilts up when the laptop is opened up. More usable screen real estate there.
