The reality is that most have used Windows for quite some time. They just don't have a tolerance for making excuses for Windows bugs and bullshit. That's why they changed their OS.
I can perfectly well fix any of these rare problems, often in seconds. And still I find every single one obnoxious and a valid reason to shit on Windows. Even more so as some are not actually bugs but intentional sabotage of a competing OS.
The simple fact that I need to think about measures to minimize the possibility of Windows screwing up dual-boot and also need to know how to fix it, if it happens none-the-less is rediculous. That's completely independent from technological literacy.
