I've had several application updates show up and some say........... "Optimized for 4th Generation iPad" So, what do you think this optimized for iPad 4 really means? Is it just BS? Or, is there some graphics/processor intensive upgrades put in place for the increased performance of this iPad? I seem to notice it on the more graphics intensivie applications (i.e. Asphalt 7: Heat v 1.0.4). What do you think?
