Full disk encryption is (thankfully) becoming a bad example. Apple has been pushing it aggressivily and both iOS devices and Macs have full disk encryption by default.<p>It&#x27;s a shame that it&#x27;s not default on Windows or Android yet, but it unfortunately makes sense since they have to run on so many different configurations (unlike Apple which can ensure that everything running their OS&#x27; are capable of full disk encryption without a noticable performance hit).
