I never said it’s perfect. In fact, I don’t use Wine for gaming at all, but the fact still remains that Wine got A LOT better after Valve got involved.
Agree on the unsuable part. I can even be a witness to that (no Windows drive API, USB is out if the question). But, regarding “regular” apps, yeah, it does the job. If you wana run Adobe or AutoDesk products, yeah, it’s no good (depends on the version, but no good for anything above 2018, 2019).
Regarding iTunes… if I was on the Wine team, I wouldn’t even consider that for testing… good thing I’m not.
