I'm starting to see 2020 M1 MacBooks CA$350 on Facebook Marketplace. That's the device I'm using to type this out. It still lasts all day, and it's still the only computer I use.
I use a 16gb ram 1tb ssd 200USD m1 macbook air. Works great!
The fact that it’s listed is meaningless. You need to ask the seller what’s wrong with it.
My daily driver is a refurbished Lenovo Thinkpad T14 gen2 with R5/16/512 GB. 360e last year from a trusted retailer with a 1y warranty. I expect I'll be happy with it for some years, as my previous T450s is still running as a homelab.
I also just acquired a 2014 MacBook Air for two packs of coffee to use as a distraction free tty writerdeck and toy around with, as it's my first piece of Apple hardware.
