That's likely because not all drivers are created equally. i have a windows 10 device with no driver problems as well, and others i have ( yoga 900 ), can't watch videos in edge, and the display driver constantly crashes. On my XPS 12, the drivers are always crashing, and the websites flicker ( also using edge ), in fact, the one with the least amount of problems is probably my SP4, that's still besides the point. you're basically saying because of software the SP4 is flawed, it can't be, that's not how it works. You would , based on this logic of yours, need to go to a new operating system. Even if every device you received worked fine, the flaw is still in the software, not the hardware.
Just in case your confused.
Software issues can be resolved by updates / changes in code, i think you know this because you mentioned " waiting ".
Hardware issues can not be resolved by updates / code, without buying new hardware.
with that said, I still don't understand the justification for blaming a physical tangible object for poorly written drivers for an operating system.
