Sadly support is fairly good but IMHO not there yet for a daily driver: https://asahilinux.org/fedora/#device-support. Microphone and external displays are not working. Plus, you rely on macOS for firmware updates.

An AMD ThinkPad has nearly the same performance, and much better software support thanks to x86_64. The compromise is decent but not great battery range (7-10 hours), mostly because of an older fabrication process.

With that said, I prefer the quality of MacBooks and Apple customer service here in EU is miles ahead of Lenovo (outsourced, crazy prices). So a viable alternative would be awesome. Some Intel MacBook Airs used to be fantastic Linux devices.

Note that HDMI out supposedly works on the pro, so the missing functionality is just the microphone, touchid, and thunderbolt/usb4. (Unless you have a usb3 display or really like dongles).

I am happy to dock my laptop to one usb-c dock and not have to deal with hdmi, mouse, keyboard and jack output every time I come to my office.

For most users Linux Asahi is only usable as a daily driver in non pros contexts on Mac Laptop and you'd be better of dedicating a computer (a mac mini?) for the office.

I wouldn't call it "pretty well" even though I applaud Asahi team for their efforts.
