Not many changes were made to the insides of the 11″ notebook, other than a totally new Airport card in addition to other minor tweaks. As for the battery that can be found in this device, it is said to boast of an increased capacity of 6.7% despite having the same amount of physical space to work with, but one could say that the increase in battery life can be mostly attributed to Intel’s latest Haswell processor that would introduce a more efficient use of its processor. The battery pack itself has increased to 7.6V and 7150mAh from its 7.3V, 6700mAh configuration previously. Well, are you willing to drop a grand to bring home the new MacBook Air, or do you think that the changes did not live up to your expectations to warrant a purchase?
