What are you people doing with your PCs? I don't mean it rude, I'm just curious. I admit I'm just regular home PC user, playing games, watching videos, doing some lame audio editing, nothing too serious. I just installed opensuse with btrfs some 4-5 years ago and never had single FS related problem since then. On the other hand it saved my ass multiple times either when I fucked something up or couple times when certain OS update didn't work well with my PC.
I'm not saying it's bulletproof, shit happens all the time, it's just... Maybe I'm lucky? Just a fun fact: My PC at work with windows had way more problems (including filesystem ones) than I've had at home during said time.
