Those who are complaining are missing a big factor related to the battery. Apple increased the battery size when they released the retina iPads in order to handle the increased power demands of the screen. I believe they also increased the wattage of the chargers from 11 watt to 13 if I'm not mistaken. But charging time increased significantly. Do you remember how people started complaining about how long it takes to charge the retina iPad compared to earlier versions. Now that the processors use less power, Apple is able to decrease the size of the battery while maintaining pretty awesome battery life of 10 hours. With a 15% smaller battery, charging times should decrease significantly. Thus, we aren't stuck waiting forever for our iPads to charge. I for one am very happy about this.
