You could use Asahi Linux if you’d rather not spend more money! Pretty good in my experience with an M1 13” MacBook Pro

I second the recommendation for running Asahi on your MacBook. I've been running it for years and it's great. The hardware support isn't perfect (Apple has nicer trackpad drivers for their hardware), but it's like still very good.

Personally the only laptop I’d be interested in that isn’t a MacBook is the Framework 13 pro but those ram prices are rough.

If you don’t want the M1 anymore, I’ve been wanting to give Asahi a try…

I’d go Lenovo over Dell

As someone else mentioned the framework pro is a good pick and also the cool new kid on the block with the repair and upgradablity(however you spell that). However spec and build quality wise, any high end business laptop will have full linux support since their be used for IT/software dev and robust enough construction to not break in a few years

That Dell looks good, ive heard good things about the new Lenovo too, really just go with whichever option is cheaper

Check out Tuxedo Computers, and StarLabs. They have some decent laptop hardware.

But the bigger question is, why are you looking to replace the machine? Apple Silicon is very powerful already, and you’re still supported by Apple on macOS.
