Low key-travel to actuation is fine (and actually makes for faster typing), but there needs to be a soft "damping" stop past that to cushion and rebound the fingers, otherwise it feels excessively rough and abrupt to type on.
Then again, seeing how many people just can't seem to type without looking at the keys, or barely use the keyboard at all, it's not surprising that evolution has removed the features of keyboards that don't give any advantage for them.
