Unfortunately it turns out that I depend on too many desktop apps that runs on the major desktop OSes but not on Linux (or on Wine, for that matter).
* KakaoTalk, the major South Korean IM app ran on Wine for a week, but the updater doesn't work and freshly reinstalling the app broke Wine for some reason. (I tried removing the whole ~/.wine prefix, but it doesn't work.) Now I'm stuck without KakaoTalk.
* Discord is only provided as a x86_64 Deb file and a .tar.gz file. I tried using it from Firefox, and it works fine but audio sharing during screen sharing doesn't work.
* Disconnecting from my Bluetooth AirPods somehow does not stop my music. I'm not sure if this is an AirPods limitation or a Linux limitation (since I've never used AirPods with Windows), but it annoyed me endlessly.
* USB-C DP mode and the fingerprint sensor doesn't work. This is an Asahi Linux limitation, but I've seen various parts of the hardware not working when using other Linux distributions on laptops as well. I feel this is a common occurrence.
Not to mention that the lack of text editing shortcuts that macOS has, which is a big deal to me (but I tried as that is a macOS-ism).
I carried my MBA for 4 days before I gave up today. I brought my MBP today with me.
