Yesterday at Apple’s annual developer conference, WWDC, the company revealed a refreshed version of the MacBook Air, the company’s thin-and-light Ultrabook competitor. Both 11-inch and 13-inch versions are getting Intel’s latest Haswell chips. Apple claims 9 hours of battery life for the 11-inch Air and 12 hours for the 13-inch. While critics have called Ultrabooks ‘MacBook Air Clones’, Apple may be falling behind.
