I love the concept of the Touch Bar. In practice, I never use it and it's not uncommon for freezing to occur when I'm trying to adjust the volume which really colors my perception of the whole thing.

I think the target market should be for non-professional users (who don't otherwise use external keyboards and have shortcuts memorized) which is why it's weird that it's a top of the line addition (obviously, a cost issue).

But it requires each application to write custom code to support. In a world where companies chose Electron over proper native development that is a no-go.
