Where the dual core processors come into play is for multitasking and when apps are specifically designed to take advantage of both cores. Unless Apple redesigns iOS to support true multitasking with apps actually RUNNING in the background (instead of just frozen state) only a select few apps will really be able to utilize the power of the dual core. This is why all the new Android tablets are getting it, because they do a lot of multitasking.
