Last fall, Apple updated the MacBook Air with a smaller body, sharper Retina display, larger trackpad, and added Touch ID. It was a solid refresh after Apple neglected it for a few years to concentrate on the MacBook Pro .
Retina display now supports True Tone; Quieter keyboard; Touch ID sensor; More affordable than before
Slower SSD versus 2018 model; Marginally faster performance; Good; but not stellar battery life
