At today's WWDC keynote in San Francisco, California, Apple announced new 11-inch and 13-inch MacBook Airs, which have been designed with battery life in mind. As expected, the new Airs use Haswell processors that offer enhanced performance and significantly improved battery life, but feature no cosmetic changes.
With the new Haswell processors, The 11" MacBook Air will now have nine hours of battery life while the 13" MacBook Air will have a stunning 12 hours of battery life.
In addition to Haswell processors, the new MacBooks feature 802.11ac compatibility, with support for the "Gigabit WiFi" 802.11ac specification. Gigabit WiFi offers speeds up to three times as fast as existing 802.11n wireless networks.
The 11" MacBook Air starts at $999 with a 128GB hard drive and the 13" MacBook Air with a 128GB hard drive starts at $1099. Apple's MacBook Airs are available today from Apple's Online Store and at retail locations.
