Choosing between the 13-inch and 15-inch MacBook Air: A guide.

Apple's new 15-inch MacBook Air joins the 13-inch model introduced last year, offering almost all of the same hardware with a significantly larger display, yet there are still some key differences that are important to consider when purchasing one of the machines. The 13- and 15-inch ‌MacBook Air‌ models are almost exactly the same in terms of feature set and design, both sporting high-resolution Liquid Retina displays, the M2 chip, Touch ID, two Thunderbolt ports, and much more.
