I acutally cancelled mine...I figured if the mouse is released this weekend, I won't actually get it by mail until the following week, making more sense for me to just go the store and see if I can snag one there... Unless, Apple does an iPhone type release and makes sure the mouse arrives at people's houses the same day it goes on sale -- which would mean they should've started shipping by now but I haven't heard anyone excitedly report such a thing yet.
