Before anyone flames me for posting another speculation thread, at least listen to what I have to say. 1) The iPad is the one product Apple has left (other than iPods) that holds an almost-monopoly in its category. Very little people buy tablets other than the iPad. Now that the first Android quad core tablets are set to appear with Kal El in September, the iPad can't afford to be left behind. 2) The iPad is the first choice for businesses, should they require an ultra-portable computing solution. Currently, they're used in doctor's offices to take notes, in conference rooms to view PPTs, and other less powerful roles. If the iPad is loaded with a quad core, people could take advantage of the incredible horsepower available to perhaps write EKG apps, or mobile MRI imagers. A quad core would make the iPad much more practical for professional applications. 3) Old iOS apps will run just as well on a single core A4 as they will on one core of a quad core A6. iPad 2 apps will run just as well on 2 cores of the 4 core A6. If the dev wishes to, they could employ the quad core horsepower to write more complex and intensive apps. 4) Given the 2048x1200 displays and matching ultra-res icons that Apple's been playing with, I think it's reasonable that Apple will be adding a high resolution display to the iPad 3. In order to drive this display, a quad core processor with an upgraded GPU will be needed. Ideas?
