In macOS I kinda enjoyed the touchbar, although I found shortcuts still much faster in e.g Photoshop. Unfortunately I need to do most of my work in Windows either through parallels or bootcamp, and as a replacement for F keys it's pretty terrible. Having no feedback and not needing to press means it's easy to miss the "key" or hit it accidentally e.g. I tend to rest my hand over F9-F11 in visual studio when debugging, and that's not something you can do without obviously triggering the key. No physical Esc key is not nice either. I ended up taking my Mac back which was really heartbreaking as in every other regard the new MacBook Pro was perfect. If they add force touch style feedback to it and actually require a press I think that would help immeasurably.
