One of the main reasons Apple has not implemented something like this is that they A) try to retain backward compatibility B) don't outfit the devices with enough RAM. The iPad 2 and Mini only have 512 megs of RAM. With that in mind, note that just displaying a MapView can easily consume between 40 and 100 megs of RAM it gets real tight real quick. Open a few apps that use a decent amount of RAM while having tabs in Safari etc. and you're going to start getting a lot of crashes. They may have to start deprecating a bunch of devices if they want to add this feature. "But it works now" NO, it "kinda works" - with the right mixture off apps / conditions it will run out of memory and crash.
