When you put it this way, it's a spin. Multiple cores make none of this easier. More efficient ? Yes, depending on use-case. Easier ? Not in any way. You still need to do thread/task separation as you would do it on a single core processor. Beyond that, it's all about priorities (yeah, if only iOS was snappier and did not have these laggy, 10fps animations... oh wait). I mean, Android and iOS both downplay multitasking because they don't really trust developers can deal with resource management. And suddenly someone says that they will write perfectly balanced multithreaded deadlock-free code, which is rocket science compared to memory management and such. Multicore will have it's uses, but not in this sense. I have no qualms that these will be snappier, but that will be more to the A9 design and upped graph chips, not multicore - but that is what will get hyped as it's an easier sell (we already see vendors linearly adding up clocks and MIPS).
