My mother asked me to switch her over to Linux about a year ago. Never had an issue since. It wouldn't have been possible without the work wine and steam have done to make playing games on Linux possible.
I've long made using Linux a condition for free IT support. I assist with switching for the willing. It reduces the amount of support I have to do which allows me to support a lot more people. ☺️
To be clear, while Linux has won much of the mobile market - FreeBSD still has roughly a third of the market worldwide, and more than half in the US for an example.
