I've thought the same but I'm not really sure what else I'd want in my laptop. With the M1s they've just hit such a sweet spot.

Battery life is great, the laptop is fast enough for everything I need. TB 3 hubs allow me to use external peripherals, two 4k 27" monitors, plenty of real estate.

Update: I just saw a couple other comments – camera for sure. A much better camera than the garbage they include nowadays.
