Recent generations of MacBook keyboards have been plagued by issues that have had users going back to Apple Stores for repairs. Apple has been replacing keyboards in most cases without much question and quickly, usually within a few days, and even if AppleCare has expired.
However, things may be speeding up as Apple Stores will now be completing keyboard repairs in-house, according to an internal memo. This is probably in an effort to make customers happier, and also to reduce the costs of the repairs.
