Took them long enough, and covers a bunch of models. On the other hand, this is an encouraging sign for future hardware revisions–maybe they will actually care about keyboard quality over thinness.
(Personally, I’m a bit miffed that typing on my MacBook Pro makes enough noise to be heard across an office, and find the feel much worse than on the MacBook One, but am glad to have had only marginal, transient issues so far that I was able to fix with a blower.)
