Why not wait on 3ed party smart type cases?

Since the magnets and auto/off are built into the iPad 2 3ed party covers/cases could be a very BIG deal. I believe in just a few short weeks we will see a multitude of innovative case features that take advantage of the magnets & on/off features not obvios at this time. With the magnets and auto on/off there WILL BE some very creative designs coming soon. Maybe even some type of integrated App/case with the magnets & on/off (depending on what can (and Apple allow to) be done).

Anyone have any practical/unique/useful ideas to what can be done?
