I had a Zoom call this morning so I borrowed an M1 Air and installed the native Zoom software. Performance was fine and battery usage for a 1+ hour call was 10%. If this were on my old 2015 MacBook Pro 13, I think that it would have used at least half the battery and the fan noise would have been a distraction. The M1 Air is a truly remarkable system. I'd go out and buy one if it came in 15 inches and had some more ports.
