You're in luck, since the 2018 MacBook Air has function keys instead of a touchbar! It's also a little bit faster and now has a high resolution retina display. It even still has a headphone port.
The press around Apple products has been concerned about them disappearing with the push for AirPods. Some articles chose to make the distinction that it wouldn't happen unless they added a Lightning port to the MacBooks, but the latest iPad Pro went from both a Lightning port and a headphone jack to neither one.
Once this machine kicks the bucket, I may just buy another of the same one instead of upgrading (if they still sell it by then).
