It will take few more years before people start abandoning W10 due to security concerns(somehow "hackers" always find some insane backdoors and bugs in old windows, it must be a pure coincidence), hardware upgrade or just need to reinstall. But indeed, it looks like Linux is finally taking over. I'd say that beside Microsoft being so bad at their job, it's Valve and gaming on Linux in general. It's actually doable. What a miracle!
