The smudge hack is only relevant if you have a continuous swype on the screen. If you allow lifting your finger and poke several things you have limited this hacks effectiveness, as people may see where you poked but not the order. So "tap your dogs in a certain order" weakens this hack. Also it seems to assume you are doing nothing else n the phone. When I open the phone I generally do something which leaves additional smudges. So someone will not know if they are the password or activity. Like it or not, I like the innovation. The best would be if you had a choice of lock screens and one chooses the style you like.
