The MacBook Pro's shallow key travel has been one of the many complaints about the laptop's keyboard to date, and that hasn't changed with the latest update. Apple does say that the "butterfly" keyboard design has been tweaked to make the keys quieter. Reports also suggest that the design change is meant to alleviate some issues with debris getting trapped under the keys and leading to keyboard failure (an issue that recently prompted Apple to launch a repair program).
By contrast, the keyboard on the ThinkPad X1 Carbon is comfortable and quiet, and features key travel of 1.8mm. That's a big plus over the sub-1mm key travel found on the MacBook Pro.
