Ah ofc I forgot. But iirc not everything works and battery life will probably suck, no? So not really a consideration in this case of price comparison. It is an option though :)
Personally I also can't stand the exterior design, albeit overall hardware of MBP is good. Guess if I land an old MBP this is what I'd do with it.
AFAIK Asahi development needs some hypervisor features for reverse engineering macOS drivers that only exist on M1-M3 and were removed on M4+. So yeah, it may be several years until they get support (or never, if nobody steps up to do it).
Big enough that they specifically targeted that exact group with this laptop.
