Vlad Savov, writing for The Verge:
When Apple redesigned the MacBook Air in 2010, it created one of the best machines to ever carry its Mac label. That new laptop was a revelation: extremely thin and light, like the original Air, yet also powerful enough for most tasks and equipped with a long-lasting battery.
I agree, when it was first released, the MacBook Air was incredibly groundbreaking.
For years, the MacBook Air has been a standard-bearer, the role model for every Windows ultrabook, but 2015 has not been so kind to its leadership position. Apple introduced the new 12-inch MacBook and updated the 13-inch Retina MacBook Pro, both directly competing with the Air, and for those not umbilically attached to OS X, Dell’s XPS 13 offered a compelling Windows alternative. And this week there’s the looming threat of the iPad Pro on the horizon.
I actually wondered how long the Macbook Air had left when they announced the new 12-inch MacBook, then I read this:
Apple is not a company that can be accused of doing things thoughtlessly, and the decision to leave the Air’s display at the lower quality and resolution must be taken as a deliberate one. In other words, Apple is comfortable with keeping the Air as a technological straggler in its lineup. That leaves us with a choice of two most likely scenarios: either the Air is destined for a future overhaul and its first redesign in five years or it has no future at all. There’s not enough room in Apple’s lineup for a MacBook, a MacBook Air, and a MacBook Pro — the MacBook is Apple’s ultraportable machine of the future and the MacBook Pro is the do-it-all laptop of today. The MacBook Air’s position seems tenuous already, and if the alleged iPad Pro does indeed materialize, then we may as well bid adieu to the Air entirely.
It's hard to argue with this logic.
