My first impression is that it adds unnecessary clutter to the interface, and is confusing to users because it is functionless in the lock screen (as opposed to being a menu item when the OS is unlocked).
Are there any designers out there who can help me understand the decision? Given the care Apple puts into their designs, I assume that I am missing something. :)
