At Monday's Worldwide Developers Conference in San Francisco, Apple announced a refresh of its line of MacBook Airs: they'll keep the same exterior, but the machines are getting improved guts to make them run faster and more efficiently.
Available for sale on Monday, the new line of ultra-thin laptops will have the same familiar aluminum outside with improved battery life and processing power on the inside. The larger of Apple's two MacBook Air lines, the 13-inch version, will have the juice to last 12 hours instead of the previous 7 hours. The 11-inch computer's battery life was upped to 9 hours from 5 hours.
Intel's Haswell processor, a previously rumored feature of the new laptops, assists in the longer battery life and improved graphics performance, up 40 percent from the old Air models, according to Apple.
However, one feature Apple fanboys have long wanted to appear on the Air -- the richly-detailed Retina display available on Apple's MacBook Pro line of laptops -- wasn't mentioned on stage at WWDC and doesn't seem to be coming to the new computers.
MacBook Airs with 128GB of storage will start at $999 for the 11-inch model and $1099 for the 13-inch model. At $1,299, the faster, 256GB 13-inch MacBook Air will cost $100 less than previous models, according to TechCrunch.
