An interesting feature of windows 8 is true multi-tasking. Unfortunately MS has decided upon a weird 1/4-3/4 fixed split screen ratio that is not greatly useful, despite the ability of win 8 apps to wrap within the 1/4 screen space. I think true multi tasking in ios would be very useful. Imagine having an ocw video and pdf app opened side by side. Do you see true multitasking coming to the small screen, or is it somehow not aligned with ios's emphisis on functional simplicity
