The new system design I want to see is an update on the 11" MacBook Air or the 12" MacBook. I'd like to see if they can get a clamshell with good battery life and decent performance under two pounds and just wide enough for a full-size keyboard. The 11" MacBook Air is still my favorite laptop I've ever owned; I'm sad they discontinued it and didn't refresh the design. Maybe it can come back with an M1 or M2 chip, though.
