Definitely thinnest. Still terrible. I don’t recall if they even attempted “best ever” with that keyboard. I suppose perhaps they would have said that about the laptops that included these keyboards …
My point is “thinnest” can be true without being “best ever.”
Touch Bar - most intuitive ever?
Butterfly keyboard - thinnest ever?
Bendy iPhone - lightest ever?
Antennagate - sleekest design?
