Linux had been my primary OS for over two decades and modern Linux is at least as pretty as win10 and I prefer its font rendering (there will be a degree of familiarity favouring that I'm sure).

You keep bringing up these arguments as though they are show stoppers and yet people using Linux as a desktop never mention them.

My mum's been on Linux since 12.04 and has never once said "You know what I need DirectText" users don't care how text gets on the screen only that text gets on the screen.

Edit: should mention she doesn't just use it as a glorified browser container she uses libre office, gimp and a few other programs, organises her music and all the stuff an average user her age would do on windows.

To her it is entirely a functional windows replacement, enough that when I upgrade her machine her request was "can I have that minty thing?"
