Yeah I can agree with this mentality from the general public. Their tablet or phone doesn't just randomly stop working or lose the display or whatever, so why should their PC.
the problem is, and you pointed it out, is that unless the manufacturer has total control over the OS, hardware and I/O devices (like apple) then there are simply going to be glitches. Windows 10 is the best and easiest version of windows ever and lots of people still have lots of different issues. But thats what happens when there is literally millions of combinations of components and I/O and display devices available to you.
