I'll wait until the second or maybe even third generation and go from the last year's 16" Pro to Air, but only if it runs Linux flawlessly (= at least as well as the 2015 Macbook).
Apple hardware is the best available, I tried Dell XPS, Lenovo Txxx and the Xs and HP Precision and all of these felt like I went 10 years back - today's models are still not comparable even to the 2015 Macbook (except for better CPU, but I throttle it for battery anyways).
