You might be surprised to learn that Apple still sells the older MacBook Air, a model released in June 2017. It's essentially the same design that Apple introduced way back in 2010. It has 2017-era components -- probably not your top choice in 2019 -- but also a revered keyboard and a time-tested build. (Read the full MacBook Air 2017 review here.) 

And though Apple sells it for $999, it can usually be found for $900, and sometimes even less. (Note that CNET may get a share of revenue from the sale of the products featured on this page.)
