They run Linux actually very well, have you ever tried Parallels or VMware Fusion? Especially Parallels ships with good softwaer drivers for 2d/3d/video acceleration, suspend, and integration into the host OS. If that is not your thing, the new native container solution in Tahoe can run container from dockerhub and co.
