While people were smitten by iOS7 release, Apple launched an improved MacBook air at Apple's WWDC 2013 event. The new Macbook air v11 and 13 comes with tons of improvements. The changes are not very big but important enough to make cater the current strengths of the device. With the new Intel processors, Apple is promising 12 hours of battery life for the 13.3-inch model, and 9 hours for the 11.6-inch version. If you're comparing it with previous versions then there has been a significant improvement over the battery life, as last year’s Air models have just 7 hours/5 hours of battery life. The new MacBook air is faster, lighter and cheaper.
