I switched to Mac with the Intel change around...2006 maybe? Converted my entire family.
I personally switched to various flavors of linux around 2016-2017 because I wanted more hardware options.
Eventually, my son got into gaming and eventually we let him get an Alienware laptop maybe 2-3 years ago. Then my wife had to get one for work this year. It's like nothing has improved in 20 years.
Naively one would think that the single greatest market force on Windows would be its users making informed decisions and migrating to better OS options. But continually they don't. So it's clear that Windows' own merits are not what shapes those market forces, but a complex ecosystem of gaming, IT departments, and a long tail of other things difficult to enumerate.
