It's good, a lot of good work going on, what they already have is impressive and the development seems pretty active and progressing well.
But if you're buying a laptop to run Linux and don't plan to use macOS, I really think there are a lot of better options out there (depending on what's important to you). You're going to pay the Apple premium price for a computer, and though apple computers are good hardware, they're expensive and largely overpriced for small upgrades. Whatever price you find for a refurbished M2, take that money and go find a laptop known to be well supported on Linux, it'll just be a better experience and you'll probably get more for your money.
I haven't run Asahi in 6+ months but thunderbolt/usb4 wasn't working when I last used it so I couldn't use my usb dock. Video was OK but I think Audio was sketchy (don't remember specifics). It's stuff that will get fixed at some point but right now it feels like a handful of minor annoyances or inconveniences
Even in 1-2 years when Asahi gets some updates and is in a better spot (I really do expect it to be) I still don't think I'd lean towards a macbook with Asahi over something else if Linux is the only OS you're going to run. Of course, if you're looking to dabble with some iOS development or something else you need a mac for, but don't want to live in MacOS, then Asahi's a great option to get you back to Linux.
