And to that end: If you're using JSHint with all of the quality options turned on, then great. You're writing strict mode code and you won't have strange errors and you'll get all of the speed benefits.
But not everyone is using JSHint or the like, so strict mode is one more avenue to help prevent errors before they happen (and force some optimizations).
