My main issue was the loss of _tactile_ F keys - hard to touch type when you're finger mashing a narrow touch screen

Not on the 13" no but they could have made the touch pad slightly smaller.

For me touch keys will never work, like the other poster said I need tactile feedback. Apple's keyboards are pretty bad at that already by the way, even the return to scissor models. The only ones I find workable are the ones of 2015 and before.
