I'm starting to think it takes Apple about 2 years to react to things needed on the platform. 2 years ago, the first of the apps went under development for release that summer. And now they are addressing the lack of 3rd party multitasking. Cut and paste was missing from the initial device, and came in 2 years later. What got me thinking about this is that nothing today really addressed the notifications issue. Push messages for 3rd party apps only came in to the SDK a year ago, so it may take until iPhone OS 5 to really sort that mess out. And until then, OS 4 is only going to make it worse, with backgrounded apps able to send local notification alerts.
