Earlier this week Apple surprised us with a bunch of MacBook Pro upgrades, but what most potential buyers wanted to know was whether the refresh fixed the problem Apple has been having with its laptop keyboards. Well, it looks like the answer is: maybe.

It seems safe to assume that this is designed to stop dust and other particles from getting under the keys and stopping them from working correctly.
