4 MacBook Air

The MacBook Air is also being sized out of its own category. The lineup was once Apple’s thinnest and lightest, but has since been dethroned by the new ‘MacBook’. Once rather revolutionary in its form factor, its relevance is obviously declining as all of Apple’s MacBooks are getting thinner and thinner — even its high-powered MacBook Pros. The MacBook Air was refreshed in March 2015, and then slightly refreshed again in 2017, however rumor has it that Apple is planning on discontinuing the product altogether.
