Things like handling gracefully video card/dual monitor, audio switching, and sleep mode recovery end up being headaches that use up a lot of time googling around and generally learning about stuff you shouldn't have to know.
It would be nice to see a company that specializes in a linux flavor sell a machine that is specifically built for that OS and with high build quality. Chromebooks are the closest thing to that but pushing a web-only interface is a major drawback.
Are there any serious projects in this direction?
