Years ago I got a Surface Book. By the end of its three year warranty, I was on my fourth unit: the first was replaced after almost two years due to a couple of broken keycaps (left Ctrl, and S or D was most of the way to split), minor battery bulging, some screen discolouration at the bottom edge, and there had also been slowly increasing connectivity issues between keyboard part and top part; the second was BSODing from the start, basically DOA; and the third stopped recognising the top part’s battery after nine months. The fourth unit was in poor shape by the time it was two years old (similar issues to the first unit), I replaced it before it was three, and a couple of years later when I tried to start it it wouldn’t finish booting. The power brick had developed issues over time too.

For what I wanted at the time, all that was acceptable. But as a first-generation product of a new category, I wouldn’t have tried it without that three year warranty. There were bound to be issues.
