I wonder if Apple will follow jailbreaker UI when if and when they introduce a true multitasking/windowing system on iOS. They did so with multitasking and mission control UI designs. I doubt Apple would introduce true windowing however, they seem to keep a large development/design crowd away from Android simply because developers only have to target a couple of screen sizes/aspect ratios.
