I investigated this path. In terms of comparable performance per watt komapnio laptops are competitive. But not on price. Then there's the aspect of how open/closed each ecosystem is. While iOS is an prison like ecosystem, macos still remains quite open, more open than many chromebooks.

Asahi linux exist and i was surprised to see that these arm chromebooks just lack bios/uefi that allows me to install anything other than chromeos.

So, yeah, you can virtualize other OS on chromeos but so can you on macos
