What exactly would the use of quad core be on an ipad, a device which touts "power-saving" as one of its features? Any app which requires that much resources would drain batt life like crazy!

Fail. CPU cores can shut themselves off if unused (making their power usage almost none). Thus if all you are doing is surfing, then only one or two cores would be active.
If this wasn't true, then the iPad 2 would have significantly less run time compared to the iPad 1 that had half the cores (and a lot less features).
Further, the next generation of ARM CPU's will most likely incorporate two high "powered" CPU cores, and two low "powered" CPU cores. Thus again, if only doing basic functions, the low power CPU cores will only be activated and the power draining cores will be turned off. Also, most likely there will be a die shrink in the next generation. Each die shrink traditionally brings with it lower power usage.
There have been about a dozen or so articles on macrumors alone already discussing how the next generation quad core processors will handle power gating to keep the power usage in the same realm as the current generation.
