Agreed. But I would love to use that space rather than on the tank or on the tail. Seems ideal for weight distribution if you are not inclined to lean over a tank bag. And I don't want to leave the alum panniers on there unless I need to cavernous space they offer.
Just found this one and order the standard black version. Figured if I am going to spend that kind of money, it would make sense to get something that locks and is completely water-proof. And I like the idea that my EZPass thing can be left in there.
