Apple is said to currently be considering the launch of a new MacBook Air notebook PC with a 14-inch display. Citing unnamed sources within Apple’s supply chain, DigiTimes on Wednesday reported that Apple is considering a 14-inch ultra-slim laptop computer to better address consumers in China, where 14-inch models have between 35% and 40% of the portable computer market. The site had previously reported that Apple is working on a 15-inch MacBook Air model, a claim that a number of other reports have mirrored. DigiTimes first reported that Apple will launch the 15-inch Air in the second quarter this year, but then issued a new report two weeks later stating that the 15-inch model was slated to launch in the first quarter of 2012 alongside new 11-inch and 13-inch MacBook Air models. It is unclear if DigiTimes is now suggesting that Apple will launch a 14-inch model in China and a 15-inch model for the rest of the world, or if the company is considering replacing the previously-rumored 15-inch model with a slightly smaller laptop.
