The Linux desktop will arrive if we just wait for Microsoft to keep making Windows worse. Linux doesn’t have to get better. MS just needs to incorporate more ads.
Depends on the ISP. E.g. a lot of Verizon/Frontier FiOS residential customers don't have ipv6. Google statistics say USA is ~47% ipv6. Frontier FiOS is less % than that.

Google's statistics: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...
99.9% of the time, modern Linux works out of the box everytime.
So I'd say it's on par with Windows versions, except I practically never need to download install drivers, or to face ads.
Maybe I'm on a different planet on which the year of the Linux desktop has arrived for longer than a decade.
